# Characterization of Flax and Hemp Using Spectrometric Methods
## 5 Conclusions  
The data reveal that the flax samples have the highest antioxidant capacity when compared to hemp samples. Flax samples from Romanian flora exhibit an antioxidant capacity and more investigations should be performed in order to describe the complex interactions between antioxidants and the human body. It is promising to observe that molecular compounds, such as those in hemp and flax, may be of potential interest in food and pharmaceutical research. The comparison of the antioxidant activity of the studied textile plants emphasized a hierarchy of antioxidant capacity in flax seeds and hemp seeds. The resulting data reveal that the hemp and flax seeds have the highest antioxidant capacity. We obtained a strong significant positive correlation at the \(p<0.05\) level between the antioxidant capacity and humidity content of considered seeds. With the help of FT-IR spectrometry, it was possible to make physicochemical determinations on the analyzed samples. According to the FT-IR spectra obtained, it could be highlighted that hemp seeds have a higher protein intake (1546 cm\({}^{-1}\)), the results being in accordance with Table 1.  
Additionally, following FT-IR spectroscopy, it was observed that hemp seeds have a higher concentration of cellulose/hemicellulose compared to flax seeds. This paper, which compares the two types of seeds by FT-IR spectroscopy, emphasizes once again the benefits of these plants on the health of the human body and also in the animal field. Fax seeds contain fiber, protein, amino acids, Omega-3 fatty acids, vitamins and minerals such as vitamin B1, copper, magnesium and phosphorus, and also other compounds essential for the proper functioning of the body. In nutrition, they are considered a very beneficial food for the body. Constant consumption of flax seed plays an important role in regulating blood cholesterol levels. Substances found in flax seeds, such as Omega-3 fatty acids, fiber and lignans, help maintain heart health by reducing blood pressure and relieving arthritis symptoms due to their anti-inflammatory properties. Additionally, due to their insoluble fiber content, they have an effect on blood sugar levels and a beneficial effect on regulating intestinal transit. Hemp seeds contain protein, fiber and healthy fatty acids with antioxidant effects. All the nutrients in the composition of these seeds help maintain the health of the heart, skin and digestive system. \begin{table}

Table 3: Linear correlation coefficients between antioxidant capacity and water content of tested seeds. In their composition are found essential fatty acids, such as alpha-linolenic (Omega-3 fatty acid) and gamma-linolenic (Omega-6 fatty acid). The proportion of the two fatty acids is very important for the body, and hemp seeds provide these acids in a balanced way. Hemp seeds also contain fiber, soluble and insoluble, which has many roles in the body: reduce appetite, regulate intestinal transit, stabilize blood sugar and support the health of the intestines. In terms of minerals and vitamins, hemp seeds are a good source of magnesium, phosphorus, potassium, iron, zinc, vitamin E and B-complex vitamins (niacin, riboflavin, thiamine, pyridoxine and folic acid).
