By the determination of the antioxidant system of plants and its high level lipid peroxidation led to an increase in the activity of antioxidant enzymes.The highest amount of water-soluble antioxidants was found among the legumes in soybean, with 800 µg/g on the first day of germination, and higher amount also was observed on the third day of the growing season - 620 mg/g. Vitamin C is a strong antioxidant and is also very important in redox reactions.The formation of vitamin C in barley from cereal plants in a 7-day-old seedling is 69.8 mg/%. In leguminous plants, for example, in soybean, the amount of vitamin C is greater than in a 7-day-old mung bean seedling and it is 48.4 mg /%.
