Published: June 2022

Light and nutrients are among the most important factors for sustained plant production in agriculture. As one of the goals of the European Green Deal strategy is to reduce energy consumption, greenhouse growers focus on high-value crop cultivation with less-energy-demanding growing systems. This study aimed to evaluate the effect of fertilization at different light intensities on the growth of lettuce and basil and the activity of the antioxidant system. Sweet basil (Ocimum basilicum, ‘Opal’) and lettuce (Lactuca sativa, ‘Nikolaj’) were grown in a greenhouse supplementing natural light (~80 µmol m−2 s−1) with lighting at two photon flux densities (150 and 250 µmol m−2 s−1), 16 h photoperiod, and 20/16 °C day/night temperature in May (Lithuania, 55°60′ N, 23°48′ E). In each light regime treatment, half of the plants were grown without additional fertilization; the other half were fertilized twice a week with a complex fertilizer (NPK 3-1-3). The results showed that the antioxidant activity of basil was most affected by 150 µmol m−2 s−1 PPFD lighting and the absence of fertilization. Altered antioxidant activity in lettuce in the presence of 250 µmol m−2 s−1 PPFD additional light intensity and fertilization resulted in higher morphological parameters.

The conventional plant breeding evaluation of large sets of plant phenotypes with precision and speed is very challenging. Thus, consistent, automated, multifaceted, and high-throughput phenotyping (HTP) technologies are becoming increasingly significant as tools to aid conventional breeding programs to develop genetically improved crops. With rapid technological advancement, various vegetation indices (VIs) have been developed. These VI-based imaging approaches, linked with artificial intelligence and a variety of remote sensing applications, provide high-throughput evaluations, particularly in the field of precision agriculture. VIs can be used to analyze and predict different quantitative and qualitative aspects of vegetation. Here, we provide an overview of the various VIs used in agricultural research, focusing on those that are often employed for crop or vegetation evaluation, because that has a linear relationship to crop output, which is frequently utilized in crop chlorophyll, health, moisture, and production predictions. In addition, the following aspects are here described: the importance of VIs in crop research and precision agriculture, their utilization in HTP, recent photogrammetry technology, mapping, and geographic information system software integrated with unmanned aerial vehicles and its key features. Finally, we discuss the challenges and future perspectives of HTP technologies and propose approaches for the development of new tools to assess plants’ agronomic traits and data-driven HTP resolutions for precision breeding.

Published: June 2022

Methylnissolin-3-O-β-d-glucopyranoside (MNG) is a pterocarpan analog, which protects EA.hy926 cells against oxidative damage through the Nrf2/HO-1 pathway. However, the effects of MNG on obesity-induced inflammatory responses in adipocyte-macrophage co-culture remain unclear. A differentiated murine preadipocyte cell line (3T3-L1) was co-cultured with a murine macrophage cell line (RAW264.7). Intracellular lipid accumulation was determined using Oil Red O staining. Western blotting was performed to investigate the expression of adipogenesis- and inflammation-associated proteins. Cell culture supernatants were assayed using ELISA kits to measure the levels of proinflammatory cytokines such as interleukin 6 (IL-6) and monocyte chemoattractant protein-1 (MCP-1). MNG inhibited lipid accumulation and the production of IL-6 and MCP-1 in the 3T3-L1 and RAW264.7 cell co-culture. Moreover, MNG inhibited the protein expression of CCAAT/enhancer-binding protein alpha (C/EBPα), C/EBPβ, peroxisome proliferator-activated receptor γ (PPARγ), cyclooxygenase 2 (COX-2), and inducible nitric oxide synthase (iNOS) under the same co-culture conditions. MNG also inhibited IL-6 and MCP-1 production compared with the co-culture control. These findings demonstrate that MNG inhibited lipid accumulation and inflammatory response by downregulating IL-6 and MCP-1 production and protein expression of C/EBPβ, C/EBPα, PPARγ, COX-2, and iNOS in co-culture conditions with 3T3-L1 and RAW264.7 cells. These results suggest that MNG may be beneficial in preventing obesity-related inflammatory status.

Published: June 2022

In recent years, special attention has been paid to climate change assessment and research into our changing environment. The greatest economic losses worldwide are due to the negative effects of drought stress and extreme temperature on the plants’ morphological, physiological, and biochemical properties which limit crop growth and productivity. Sweet basil (Ocimum basilicum L.) is one of the most popular plants widely grown around the world as a spice, as well a medicinal, aromatic plant. The seedlings with 5–6 true leaves were divided into two groups, and one group of seedlings was sprayed with 10 mM potassium bicarbonate (KHCO3). Three days after potassium bicarbonate treatment, half of the plants from each group were subjected to a water deficit (drought stress), and the other half were grown under stress-free conditions (well-watered). The present study aimed to evaluate the effect of potassium bicarbonate (KHCO3) on morphophysiological parameters, phenolics content and the antioxidant activity of basil under drought conditions. The application of potassium bicarbonate to drought stressed plants significantly increased the chlorophyll content, fresh and dry weight, phenolics content in the two of tested cultivars, and antioxidant activity, determined by DPPH and ABTS methods. Principal component analysis showed that the first factor was highly and positively related to all the investigated parameters. Hierarchical clustering analysis showed that the first cluster was formed by being well-watered, well-watered and sprayed with potassium bicarbonate, and grown under drought conditions and sprayed with potassium bicarbonate basil cultivars, while the second cluster was formed by all the tested cultivars grown under drought conditions.

Aluminum (Al) solubilizes into trivalent ions (Al3+) on acidic soils, inhibiting root growth. Since about 13% of global rice cultivation is grown on acidic soils, improving Al tolerance in rice may significantly increase yields. In the present study, metabolome analysis under Al toxicity between the Al-tolerant variety Nipponbare and the Al-sensitive variety H570 were performed. There were 45 and 83 differential metabolites which were specifically detected in Nipponbare and H570 under Al toxicity, respectively. Furthermore, the results showed that 16 lipids out of 45 total metabolites were down-regulated, and 7 phenolic acids as well as 4 alkaloids of 45 metabolites were up-regulated in Nipponbare, while 12 amino acids and their derivatives were specifically detected in H570, of which 11 amino acids increased, including L-homoserine and L-methionine, which are involved in cysteine synthesis, L-ornithine and L-proline, which are associated with putrescine synthesis, and 1-aminocyclopropane-1-carboxylate, which is associated with ethylene synthesis. The contents of cysteine and s-(methyl) glutathione, which were reported to be related to Al detoxification in rice, decreased significantly. Meanwhile, putrescine was accumulated in H570, while there was no significant change in Nipponbare, so we speculated that it might be an intermediate product of Al detoxification in rice. The differential metabolites detected between Al-tolerant and -sensitive rice variants in the present study might play important roles in Al tolerance. These results provide new insights in the mechanisms of Al tolerance in rice.

Published: June 2022

In the context of low rainfall, groundwater abstraction is the main source of water, especially in rural areas. For better water management, a good knowledge of water resources is necessary. The Cascades region depends, like most regions, on the use of groundwater, especially in rural areas. However, this region has been subject to a strong anthropogenic impact in recent years, in association with mineralization. This study aims to establish the status of groundwater quality in order to strengthen the knowledge of groundwater resources, for better planning of preservation strategies and sustainability of actions. Fifty-eight borehole water samples were collected using techniques and methods for assessing groundwater properties. The results indicate that the electrical conductivity (EC) values of the water show slight mineralization. The waters are aggressive, with severe-to-significant corrosion, and with calcite saturation in relation to the geological facies. Principal component analysis allowed us to conclude that residence time and leaching due to anthropogenic activities have an impact on quality. The chemical and bacteriological quality of the groundwater systems is of great concern, as some parameters exceed the Burkina Faso guidelines.

Published: June 2022

Recent advances in deep learning, including the development of AlexNet, Residual Network (ResNet), and transfer learning, offer unprecedented classification accuracy in the field of machine vision. A developing application of deep learning is the automated identification and management of aquatic invasive plants. Classification of submersed aquatic vegetation (SAV) presents a unique challenge, namely, the lack of a single source of sensor data that can produce robust, interpretable images across a variable range of depth, turbidity, and lighting conditions. This paper focuses on the development of a multi-sensor (RGB and hydroacoustic) classification system for SAV that is robust to environmental conditions and combines the strengths of each sensing modality. The detection of invasive Hydrilla verticillata (hydrilla) is the primary goal. Over 5000 aerial RGB and hydroacoustic images were generated from two Florida lakes via an unmanned aerial vehicle and boat-mounted sonar unit, and tagged for neural network training and evaluation. Classes included “HYDR”, containing hydrilla; “NONE”, lacking SAV, and “OTHER”, containing SAV other than hydrilla. Using a transfer learning approach, deep neural networks with the ResNet architecture were individually trained on the RGB and hydroacoustic datasets. Multiple data fusion methodologies were evaluated to ensemble the outputs of these neural networks for optimal classification accuracy. A method incorporating logic and a Monte Carlo dropout approach yielded the best overall classification accuracy (84%), with recall and precision of 84.5% and 77.5%, respectively, for the hydrilla class. The training and ensembling approaches were repeated for a DenseNet model with identical training and testing datasets. The overall classification accuracy was similar between the ResNet and DenseNet models when averaged across all approaches (1.9% higher accuracy for the ResNet vs. the DenseNet).

The purpose of this study was to examine the effect of a soccer small-sided game (SSG) on performance, inflammatory, muscle damage and hormonal indicators. Twenty-two male soccer players participated and were assigned to either experimental (EXP = 12) or control (CON = 10) groups. Subjective fatigue (RPE) and lactate (La¯) were measured during the SSG; vertical squat jump (SJ), 20-m sprint, creatine kinase (CK), interleukin-6 (IL-6), cortisol (C), and testosterone (T) were measured before (PRE), after (POST), 24 h, 48 h, and 72 h after the SSG in the EXP group. The heart rate during the SSG reached 92 ± 3% of their HRmax, whereas La¯ and RPE reached 13.02 ± 1.60 mmol·L−1 and 15 ± 1 after SSG, respectively. The IL-6, different among measurements (F (1.04, 11.50) = 504.82, p < 0.001), peaked (3.52 ± 0.43 pg·mL−1 [95%CI; 3.28–3.77]) after the SSG and returned to baseline 24 h later. The CK, different among measurements (F (1.76, 19.32) = 93.96, p < 0.001), peaked (536.58 ± 124.73U·L−1 [95%CI; 466.01–607.15]) 24 h after the SSG and remained significantly higher than PRE condition in POST and up to 72 h later. The T/C ratio, significantly different among measurements (F (1.73, 19.05) = 12.12, p < 0.001), was at its lowest (0.44 ± 0.16 [95%CI; 0.35–0.54]) immediately after the SSG (p < 0.05) and returned to baseline after 24 h. It seems that 48 h (at the most) after an SSG is adequate time for players to recover, and a high training load should be avoided sooner than 24 h after an SSG.

Published: June 2022

The growing burden of chronic disease represents a complex challenge to public health. Innovative approaches, such as system dynamics simulation modeling, can aid public health professionals in understanding such complex issues and identifying effective solutions. This paper describes a system dynamics model and its application in projecting the impacts of evidence-based interventions on chronic disease for the state of Colorado. The development of the model was guided by data and input from subject matter expertise, peer-reviewed literature, and surveillance data. The model includes 28 intervention levers for chronic disease prevention, screening, and management. Interventions were simulated from 2020 to 2050 to project their impact on ten preventable causes of death. The simulations indicated the 6 most impactful interventions by 2050 to be adult smoking prevention, diabetes prevention, smoking cessation, blood pressure management, adult physical activity promotion, and colorectal cancer screening. Together, these 6 interventions could reduce preventable deaths by 7.1%, or 74% of the 9.6% reduction from all 28 interventions combined. This system dynamics model is a flexible tool that could be adapted or extended to include other populations or preventable chronic diseases. Prioritization and wide-scale implementation of the most impactful interventions could significantly reduce preventable deaths resulting from chronic disease.

The article presents the materials of examination and treatment of women aged 20–55 years with keloid scar pathology before and after the use of carboxytherapy injection methods. Research methods: The data from 291 outpatient records of patients with scar pathology detected in the long-term period (4.2±1.4 years) were studied. In 92 patients with scar pathology, a dermatologist performed a clinical and functional assessment of the dermis using a digital video camera (Aramo SG, USA), which allows performing dermatoscopy and assessing both the superficial and deeper layers, microrelief and morphofunctional features of scar tissue with a score of the area of the affected skin surface: 0 — there is no lesion; 1 —< 10%; 2 — 10–25%; 3 — 26–50%; 4 — 51–75%; 5 — 76–90%; 6 — 91–100%. PCR diagnostics of immune parameters (IgM, IgA, IgG, cytokines) was performed before and after the injection carboxytherapy. Results: It has been established that the severity of keloid dermal pathology is interrelated with immune indicators, which confirms our assumption about the pathogenetic role of injectable carboxytherapy, which provides immune correction and improvement of the structure of scarring in the skin, since an indirect mechanism of action on a protein in skin tissues involved in the formation of ROS — NF-kB has been clarified. Conclusion: thus, injectable carboxytherapy with the drug «Fermencol» provides significantly more effective anti-inflammatory and antimicrobial correction, stimulation of microcirculation and metabolic processes in scar tissue, which is more reliably expressed in comparison with other methods of treatment presented in this study. Injectable carboxytherapy with the drug «Fermencol» allows to form high immunocorrecting effects, providing a significant increase in the levels of T-helper cells (Th1) by 14%, which is accompanied by correction of the immune status and improvement of the structure in the zone of keloid lesion.

Many observations have shown a close relationship between post-stroke spasticity and pain syndrome due to stroke; with regard to that, in 72% of patients, spasticity was accompanied by pain and only 1,5% of patients experienced pain in the absence of spasticity.Purpose of the study: to substantiate the inclusion of combined physiotherapy methods, i. e. low-frequency electrostatic massage and broadband modulation currents, and multimodal physiotherapy methods from the Alpha LED Oxy Light — Spa™ device, in the standard complex of medical rehabilitation to relieve pain and reduce spasticity in the late recovery period in patients who have undergone acute cerebrovascular accident. Material and methods: the paper presents the data on the inclusion of various physiotherapy methods in the rehabilitation program in the late recovery period in 120 patients with spasticity of the upper limb who underwent acute cerebrovascular accident. The dynamics of pain syndrome intensity were assessed according to the Numerical Pain Rating Scale and the Verbal Descriptor Scale, and the severity of spasticity in the upper limb was evaluated according to the Modified Ashworth Spasticity Scale. All patients were divided into 3 groups comparable in terms of clinical and functional characteristics: group 1 (40 patients), who, in addition to the standard treatment complex (exercise therapy, medical massage, mechanotherapy), were prescribed massage with a pulsed low-frequency electrostatic field from the HIVAMAT device and broadband modulation currents; group 2 (40 patients), whose therapy included physiotherapy methods from the Alpha LED Oxy Light — Spa™ device, against the background of standard therapy and medical rehabilitation; group 3 — 40 patients who received standard drug therapy and medical rehabilitation. Results. Inclusion of pulsed low-frequency electrostatic massage and broadband modulation currents in medical rehabilitation of patients with spasticity of the upper limb who have undergone acute cerebrovascular accident in the late recovery period contributes to the formation of analgesic and antispasmodic effects to a greater extent, compared to the Alpha LED Oxy Light — Spa™ multimodal effects, which is manifested in a significant reduction in pain and a decrease in spasticity.

Published: June 2022

The article examines some of the issues that arise when determining the legal regulation of trade unions of persons employed through Internet platforms in the Russian Federation. The author notes that in the current conditions of the development of society and the state, the emergence of a category of precariously employed “workers”, who, by virtue of labor legislation, are not such, creates new challenges for the formation of a system for protecting their social and labor rights and interests. An analysis of Russian legislation has shown that de facto such persons can form traditional trade unions or other alternative trade unions to protect collective rights and interests. However, on the other hand, persons employed using Internet platforms cannot use all the instruments of labor law without being “employees”. For possible progress in solving this problem, the author proposes to amend the legislation of the Russian Federation on trade unions.

Published: June 2022

Crude methanol extracts of 43 Vietnamese plants were screened in vitro for their antibacterial activity against three common freshwater fish pathogens, including Aeromonas hydrophila, Edwardsiella ictaluri and Streptococcus agalactiae. The agar disc diffusion method was used to evaluate the antibacterial activity, followed by minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) were determined using the broth dilution method. Among the 43 plants screened, eight plant extracts (Bouea oppositifolia, Wedelia chinensis, Terminalia catappa, Punica granatum, Sonneratia caseolaris, Sonneratia ovata, Ludwigia hyssopifolia and Phyllanthus urinaria) exhibited wide-spectrum antibacterial activity to all three common freshwater fish pathogens. Six plant extracts (Ageratum conyzoides, Alpinia galanga, Borassus flabellifer, Abutilon indicum, Eupatorium odotatum, and Scoparia dulcis) might be good candidates for the prevention of co-infection of E. ictaluri and S. agalactiae in tilapia whereas Muntingia calabura and Camellia sinensis could be applied to striped catfish to combat E. ictaluri and A. hydrophila. Through MIC and MBC determination, L. hyssopifolia, A. galanga, Ageratum conyzoides extracts showed a bactericidal activity to A. hydrophila, E. ictuluri and S. agalactiae, respectively, while the other extracts could prevent the growth of tested bacteria. The screening results suggested the potential application of plant extracts as alternative therapeutic agents against bacterial infections in aquaculture.
Grammar Learning Strategies Practice: An Investigation of Strategies-Based Instruction Effect on Grammatical Competence
Authors: Ismail Ismail , Dedi Dedi
Published: June 2022

Grammar competence as an essential part in learning language has to be mastered by every language learner. Students, especially in higher education, need to possess the knowledge of grammar rules to produce academic products that maintain the grammatical aspects in every task. A new notion in learning grammar by employing grammar learning strategies becomes an alternative way for students in mastering grammar. Since many students are not aware of grammar learning strategies, the need to conduct strategies training in the classroom context is a solution. Empowered by styles and strategies-based instruction, this study aimed to determine the effect of grammar learning strategies on the grammatical competence of second semester students of Universitas Muslim Indonesia. Quasi-experimental design under quantitative research consisting of pre-test, eight meetings of treatment, and post-test was employed to compare the groups’ performance in grammar test. The data were obtained by using two kinds of research instruments: grammar test and questionnaire. In analyzing the data, this study employed the independent sample t-test and frequency of questionnaire. The result of statistical analysis showed that independent t-test which compared the students’ score on post-test revealed a value of p>0.05. It means that there was no significant difference between students taught with and without grammar learning strategies. The result yields some implications of having grammar learning strategies in classroom context. The students’ personal traits and experiences put some influences on the effect of strategies training. The duration of training also put contribution toward the students’ skills in employing the appropriate strategies in solving grammar problems.

This research aims to (1) classify the forms of imperative speech of government officials of South Sulawesi Province, and (2) explain the strategy of politeness of imperative speech of government officials of South Sulawesi Province in The New Sulsel Book. The type of research used is descriptive qualitative which describes the facts that are empirically present in the speakers. The results showed that the form of imperative speech acts of government officials of South Sulawesi Province were declarative, interrogative, and optative. In terms of this form, the tendency of official imperative speech is more dominant declaratively and optatively, which means that the imperative element is implied. This can not be separated from the principle of local culture 3S (Sipakatau, Sipakalebbi, Sipakainge) which means to humanize, respect and remind each other. Furthermore, the imperative speech politeness strategies of South Sulawesi Provincial government officials include direct politeness, indirect politeness, positive politeness, and negative politeness. In this strategy, the speech of officials is more likely to be a positive politeness strategy which means that officials in the South Sulawesi provincial government are very polite in conveying imperative speech or orders. This condition can have an impact on not maximizing the command message delivered so that it makes the partner or interlocutor not optimal in carrying out the order.

Zeytinyağı üretimi birçok Akdeniz ülkesi için en önemli tarımsal faaliyetlerden biridir ve ekonomik olarak önemlidir. Zeytinyağı endüstrisi atıksuyu (karasu), zeytinyağı üretim aşamalarında meydana gelen sayısız işlemden kaynaklanan önemli bir sıvı atıktır. Karasuyun bertarafı, özellikle yüksek organik madde, askıda katı madde, fenolik bileşik içeriği ve asidik pH değeri ile Akdeniz Bölgesinde ciddi bir çevresel sorundur. Bu çalışmada karasuyun kitosan koagülasyonu ile kimyasal olarak ön arıtımı araştırılmıştır. Kitosan ile koagülasyonun Kimyasal Oksijen İhtiyacı (KOI) ve Toplam Katı Madde (TKM) giderme verimleri üzerindeki etkisi Box-Behnken istatistiksel deney tasarımı ile belirlenmiştir. Bu yöntem, üç bağımsız değişkenin (kitosan konsantrasyonu, yavaş karıştırma ve çökeltme süresi) tepki fonksiyonları (KOI ve TKM verimliliği) üzerindeki etkilerini araştırmak ve KOI giderme verimini en üst düzeye çıkaran optimum koşulları belirlemek için kullanılmıştır. Çalışma kapsamında Design Expert programı kullanılmış, gözlemlenen ve tahmin edilen KOİ ve TKM giderme verimleri arasındaki korelasyon katsayıları (R2) sırasıyla 0.979 ve 0.9585 olarak bulunmuştur. Yapılan deneysel çalışmalar sonucunda en yüksek KOİ giderme veriminin (%53) elde edildiği koşullar; 600 mg/L kitosan konsantrasyonu, 45 dakika yavaş karıştırma süresi ve 60 dakika çökeltim süresi olarak bulunmuştur. TKM giderimi için en yüksek giderme verimi (%73) ise, 600 mg/L kitosan konsantrasyonu, 45 dakika yavaş karıştırma süresi ve 120 dakika çökeltim süresinde elde edilmiştir.

In this study, SiCp particles were reinforced at volumetric ratios of 5%, 10%, 15% and 20% into the EN AW 5756 (AlMg3) metal matrix composite by using the squeeze casting method. The squeezing process was carried out for 10 seconds under a pressure of 80 MPa. The changes in the wear behaviors and friction coefficients of the EN AW 5754/SiCp composite samples were examined under1.0 N force, 5000 cycles and with a 0.04 m/s sliding speed. As a result of the experiments, it was found that the friction coefficient value increased from the non-reinforced alloy to the 10% SiCp-reinforced composite, while it then decreased in the 15% and 20% SiCp-reinforced composites. Moreover, the amount of wear in the composite material increased as the ratio of the reinforcement increased, and the highest wear occurred in the 10% SiCp-reinforced composite. This wear rate decreased in the 15% reinforced composite and then increased in the 20% reinforced composite. The deformation wear statuses of the composite materials that were used in the experiments were examined by conducting SEM (Scanning Electron Microscopy) and EDS (Energy-Dispersive Spectrometry) analyses. In these examinations, it was observed that the 5% and 10% SiCp reinforcements did not show a homogeneous distribution in the matrix, but the 15% and 20% SiCp reinforcements were homogeneously distributed in the matrix material.

Kentsel su yönetiminde arıza yoğunluğuna bağlı olarak işletme koşulları bozulmaktadır. Arızaların oluşmasında en önemli faktör sistemdeki yüksek basınç ve basınçtaki düzensizliktir. Bu nedenle yeni arıza oluşumunun azaltılması için basıncın kontrol altına alınması ve dalgalanmaların azaltılması gerekmektedir. Ancak basınç kontrolü oldukça kapsamlı saha çalışması gerektiren, maliyetli bir süreçtir. Bu nedenle basınç yönetimi uygulanmadan önce oluşacak maliyetler (ekipman, saha çalışmaları, kurulum) ve faydalar (sisteme kazandırılacak potansiyel su hacmi, arızadaki potansiyel azalmalar) analiz edilmelidir. Bu çalışmada bir izole bölgede basınç yönetimi uygulanması durumunda ortaya çıkan maliyetlerin ve faydaların analiz edilmesi için hesaplama aracının geliştirilmesi amaçlanmıştır. Bu amaçla saha verilerine göre maliyet bileşenleri tanımlanmıştır. Ayrıca literatürde önerilen yaklaşımlar esas alınarak basınç kontrolüne bağlı olarak sızıntı ve arıza oranındaki azalmalar analiz edilmektedir. Bu fayda ve maliyet bileşenleri geliştirilen hesaplama aracına tanımlanmıştır. Geliştirilen bu hesaplama aracının özellikle uygulayıcılar için referans teşkil edeceği düşünülmektedir. Bu hesaplama aracında izole bölge çalışmaları için de fayda maliyet bileşenleri tanımlanmıştır.

In the present study, the content and antioxidant potential of phenolic compounds from five herbal infusions including Aspalathus linearis, Sambucus nigra, Rhamnus frangula, Plantago lanceolata and Equisetum arvense were analyzed. Additionally, simulated in vitro gastrointestinal digestion were conducted to predict the bioaccessibility of infusion phenolics. Accordingly, Rooibos infusion had the highest total phenolic (2191.18±93.39 mg GAE/100 g dw) and flavonoid content (1226.14±93.07 mg CE/100 g dw) as well as antioxidant capacity measured by CUPRAC (3124.12 mg TE/100 g dw) and FRAP (2634.95 mg TE/100 g dw) assays. On the other hand, the highest ABTS (2351 mg TE/100 g dw) and DPPH (475.19 mg TE/100 g dw) antioxidant capacity values were recorded for elderflower infusion. Based on the gastrointestinal digestion, retention of phenolics in the infusions was found to be variable througout mouth to intestine. It can be deduced from the results that those herbs can be considered as a valuable beverage alternatives with their high nutritional value.
