1. Introduction

Antioxidants are biologically active compounds and are important in plant and animal organisms. Antiox-idants are essential for the function of natural detoxification systems to remove free radicals and radical forms from the body. Free radicals would arise as a result of chronic stress and the accumulation of radioactive, var-ious chemicals in the environment in the body [1, p. 34–36; 2, p. 556 ]. Flavonoids are only synthesized in plants and have important biological significance in the human body. The herbivorous nature of row plants de-pends on flavonoids, which depends on the growth of plants. Flavonoids cause a variety of disorders in the body. Many flavonoids improve the elasticity of the vascular wall and control their permeability. Flavonoids of some plants also have the properties of herbivores and urine.

2. Results and discussion.

The main purpose of our work is to determine the amount of Flavanophytes in the leaves of fruit trees. Therefore, we have determined the amount of flavonoids in different seasons in the leaves of fruit-bearing trees, such as shotut, peach, nuts, which have the medicinal properties(Table 1).

As you know, vitamins - Vitamin C, which is the most antioxidant feature. Vitamin C improves blood circulation in the body, normalizes cholesterol.

In this regard, we aimed at determining the amount of vitamin C in the spring, summer, and cats and the activity of the ascorbic acid oxidase enzyme in the leaves of the plants showing antioxidant properties.

Our findings show that the amount of ascorbic acid in the foliage, peach, and walnut leaf plants that have antioxidant properties has been found to be relatively higher than in the summer. That is, the leaves of the shotut are 140.8 mg%, 79.2% of peach leaf, 52.8% in walnut leaf (Table 2).

As you know, the negative effects of environmental factors and applying of the pesticides in agriculture will cause as harm to the health of the population. The human body accepts residual pesticides through the nutritional chain. It gradually begins to accumulate in different organs, especially in the liver. As a result, the metabolism in the cells changes and causes the gradual formation of various free radicals. Our department has been studying the effects of karate pesticides on rats during many years and ways of their correction have been studying [1, p. 34–36; 3, p. 93–96; 5, p. 172–174]. Plant antioxidant used in correction. The main pur-pose of our work is to find cheap and suitable natural antioxidants. Therefore, we detected the total antioxidant quantity in the plant antioxidant

factor by Rogojin method [4, p.254]. In the correction the plant antioxidant factor (PAF) was applied from extracted 3 different fruit trees of leaves in Morus nigra L., Prunus persica L., Juglans regia L. and positive re-sults were obtained. Therefore, we researched the total amount of antioxidants in a number of fruit trees. The results were shown in (Table 3).

The results showed that the highest concentration of antioxidants was found in summer that in walnut and peaches leaves than spring and autumn. In walnut leaves its content was 9.105 ± 0.05 mg/g and in peach leaves it was 9.082 ± 0.075 mg/g. There are xinons, flavonoids, vitamins B and C (4–5%), carotene 12 mg/%, various xanthines and efir (ether) oils in walnut leaves. The high concentration of total antioxidants in the extract of Morus nigra L. leaves was 4.65 ± 0.55 mg/g in the spring, it was 2.693 ± 0.29 mg/g in summer, and its quantity lowered to 0.233 ± 0.07 mg/g in autumn. We observed that the total amount of antioxidants in peaches in summer and autumn is much higher than the concentration of leaves of Ficus carica L. and Morus nigra L. plants. From leaves of Prunus persica L. and Morus nigra L. were used in the gastrointestinal tract diseases to cure. A boiling of Prunus persica L. is used to treat diabetes, skin diseases. The total amount of antioxidants in the sprig of Vitis vinifera in the summer season was 7.068 ± 0.108 mg/g, and in the leaves were 6.86 ± 0.11 mg/g. The high concentration of antioxidants in Serasus vulgaris L. was about 6.63 ± 0.341 mg/g in summer. It was about 4.632 ± 0.109 mg/g in the rod, in fruit it was about 3.08 ± 0.079 mg/g.

3. Conclusion

Thus, the highest amount of antioxidants in the leaves of different fruits was found in the leaves of wal-nut and peaches in summer. It was found that the number of flavonoids in fruit leafy leaves depends on the vegetation period. We have found that vitamin C content and high levels of ascorbic acid-oxidase activity in plants that exhibit antioxidant properties.
