Study of Ascorbic Acid Content in Shoots and Leaves of Cultivated Ribes Nigrum L.

Interest in phytopreparations is increasing due to the unique properties and advantages, namely the relatively rare side effects, cheapness, availability of plant raw materials, and the complex pharmacological effect of plants on the body as a whole. Ribes nigrum L. (Grossulariaceae) is widely used in medicine, homeopathy and folk medicine. The leaves and shoots of Ribes nigrum L. are of interest in order to establish the possibility of application in scientific medicine. Materials and methods. The objects were shoots and leaves of cultivated Ribes nigrum L., which were harvested in the Sverdlovsk and Chelyabinsk regions, Bashkiria and Perm region in 2 periods: 1st - the flowering period and 2nd - the period after fruiting. The presence of ascorbic acid was proved by TLC. Quantitative determination was performed by HPLC. As a result, the presence and content of ascorbic acid in the shoots and leaves of cultivated black currant was established. Correlation analysis showed that the harvesting period does not significantly affect the accumulation of ascorbic acid. Raw materials can be a promising source of ascorbic acid.
