###### Abstract
This color change indicates a reduction in radical concentration, directly reflecting the antioxidant's capacity to neutralize free radicals. As the DPPH solution interacts with a hydrogen-donating compound, it transforms into diphenylpicrylhydrazine, losing its violet color, which signifies the antioxidant's electron-donating power [16; 17]. The FRAP test is based on the reducing power, which is determined by the reduction of Fe (III) to Fe (II) in the presence of the tested compound. The concentration of Fe (II) can be monitored by measuring the formation of Prussian blue at 700 nm. The higher the dye concentration and therefore the higher absorbance, the greater the reducing power and enhanced antioxidant activity of the tested compound. The advantages of this method are simplicity, low cost, and low time, along with no need of specialized equipment [18]. Information on the degradability of organic chemicals is valuable for both hazard and risk assessments. Aquatic hazard classification and general hazard assessments typically rely on standardized tests for ready biodegradability. However, data from tests simulating biodegradation in environments such as water, aquatic sediment, and soil can also contribute to these samples' assessment [19]. The persistence and dissipation of active substances are measured using DT (dissipation time), especially DT50 and DT90 values, which represent the time required for 50% and 90% of a substance, respectively, to disappear. \"Disappearance\" encompasses all processes leading to the substance's transformation, degradation, and eventual mineralization, including microbial degradation, chemical hydrolysis, photochemical reactions, and other mechanisms like leaching, volatilization, and plant uptake. In soil, laboratory experiments generally consider a DT50 of less than 60 days at 20 \({}^{\circ}\)C acceptable (or less than 90 days at 10 \({}^{\circ}\)C for applications in colder regions). In field conditions, acceptable thresholds are a DT50 of less than 3 months and a DT90 of less than 1 year. It should be noted that DT50 and DT90 indicators do not differentiate between degradation processes--such as mineralization, microbial degradation, hydrolysis, or photochemical reactions--and loss through leaching, volatilization, or plant uptake. Instead, these values provide a holistic assessment of a substance's dissipation, encompassing all contributing processes [20]. In terms of adsorption, it depends on two main factors, pesticide properties and soil properties, showing the behavior of pesticide in soil. Molecular properties of pesticides like solubility, ionizability, and hydrophilicity and lipophilicity are crucial [21]. The organic carbon partition coefficient Koc was used as a key parameter to assess the environmental risk of pinocembrin dihydrohalcone. The Koc value indicates the compound's binding capacity and its potential for sorption in soil [22]. Various analytical methods are available for determining chalcone concentrations across different matrices, including chromatography with a range of detectors, MALDI, and HNMR techniques [3]. [PERSON] et al. employed an UHPLC-DAD method to identify six primary dihydrohalcone derivatives [23]. In this experiment, UHPLC-ESI-MS/MS was used to determine the DT50 and DT90 values, as well as to assess the pinocembrin dihydrohalcone concentration after the sorption experiment. The aim of this study was to evaluate the attributes of pinocembrin dihydrohalcone, including its antioxidant properties and environmental behavior, as a potential biopesticide. This could be assessed through the soil dissipation study experiment, as well as its sorption affinity to soil.
