A DETERMINATION OF THE AMOUNT OF VITAMIN C IN SOME MEDICAL PLANTS GROWING IN THE SOUTHWESTERN ZARAFSHAN MOUNTAIN RANGES
Abstract: This article involves the data about amount of vitamin C, which has an antioxidant effect, growing in the South - Western Zarafshan ridges such as Mentha asiatica, Ziziphora tenuior, Melissa officinalis, Rubus sp., Trichodesma incanum and Bunium chaerophylloides in different seasons.

№ The name of medical plants Spring Summer Autumn
1. Mentha asiatica 121 ± 2.2 92.4 ± 3.5 86.24 ± 5.1
2. Ziziphora tenuior 81.9 ± 1 58.08 ± 2.5 57.2 ± 4.1

The largest amount of vitamin C was found in Ru-bus sp., and Mentha asiatica plants in the spring season. Mentha asiatica blooms in June and August, and fruits ripen in September - October. Using organs are leaves and blooms. There are ether oil and flavonol in the leaves of Mentha asiatica [5]. There are vitamin C and ketihin besides ether oil in Asian mint. Drip and boiled solution of mint are used in medicine. The results showed, that the highest amount ofvitamin C consisted of121 ± 2.2 mg/% in spring, 92.4 mg/% in summer, 86.24mg/% in autumn.
We observed the amount of vitamin C in the leaves of Ziziphora tenuior, in various seasons. In spring its amount is about 81.9 mg /% and almost it is same in the seasons of summer and autumn. Ziziphora tenuior is the essential medicinal plant in the field of medicine in our republic. Especially, Ziziphora tenuior spread in the northern and southern slopes of mountain regions. Ziziphora tenuior is used to cure kidney, heart, and liver and stomach-intestine disorders in people medicine. The drip of Ziziphora tenuior helps to improve the activity ofheart, to decrease the arterial blood pressure and in curing of urine [4]. There are 2.5% of ether oil, vitamins of C, E, A in the stem, leaves and blooms.
Rubus sp. begins to bloom and ripen from July to September. Using organs are fruits, leaves and roots. There are vitamin C and carotene in the content of leaves of light blue Rubus sp. There are organic acids, vitamin C, plenty ofcelluloses, sugar substances, vitamin B and copper in the fruit of Rubus sp. Their branch is used by preparing boiled and drip solutions in people medicine. Our research deter-
mined that there is vitamin C in the leaves ofRubus sp. The received data showed, that the highest amount of vitamin C is in spring, consisting of 123.2 mg /%.
Bunium chaerophylloides blooms in June, ripens in July. There is ether oil of 2.75 - 3.0% in the fruit. There is about 20% of oil, 15% ofprotein substances and minerals in the fruit of it. Especially, the fruit of Bunium chae-rophylloides is used in medicine. The highest amount of vitamin C in the leaves of Bunium chaerophylloides consists of 68.3 mg/% in autumn.
A Melissa officinalis blooms in June - august, ripens in July-autumn. Using organs of Melissa officinalis are its leaves and the tip parts of branches. There are ether oil, vitamin C, urosolate and other acids in Melissa offi-cinalis. The boiled solution and drips are used in people medicine. According to our results, vitamin C in Melissa officinalis consisted of76.56 mg/% in spring, 92.4 mg/% in summer and 81.8 mg/% in autumn.
We defined the amount of vitamin C in Trichodes-ma incanum and vitamin C consisted of 29.9 mg /% in spring, 60.72 mg/% and 71.28 mg/% in summer. Trich-odesma incanum spread out in Central Asia. It keeps strong alcoholics in its contents. Most alcoholics are located in its seeds. We also found that there are alcoholics in its leaves, too.
Thus, Mentha asiatica, Ziziphora tenuior, Melissa of-ficinalis, Rubus sp., Trichodesma incanum and Bunium chaerophylloides have vitamin C and the highest amount of vitamin C is in Rubus sp. and Mentha asiatica, this amount will be appear in the spring season.
