GYNOSTEMMA PENTAPHYLLUM AND CARICA PAPAYA: SOURCES OF BIOLOGICALLY ACTIVE SUBSTANCES

Abstract

The article is devoted to the determination of the content of vitamins, a trace element - iron, flavonoids in the raw materials of Gynostemma pentaphyllum, Carica papaya and the establishment of correlations between the indicators of two signs: the content of ascorbic acid and flavonoids, in terms of rutin.Material and methods. The objects of the study were the herb of gynostemma pentaphyllum and leaves of papaya, introduced on the territory of the South Ural Botanical Garden-Institute of the Ufa Federal Research Center of the Russian Academy of Sciences and on the basis of Limonaria, the educational and experimental farm of the Ufa Forestry Technical College. The mineral composition (iron content) was determined by X-ray fluorescence method, and vitamins, flavonoids, carotenoids - by the spectrophotometric method.Results. In the course of laboratory experiments in plant objects, their absorption spectra of ascorbic acid and rutin were studied,the content of which averaged 1350±1,27 mg/%, 1430±0,29 mg /% and 2100±0,23 mg/%, 3800±0,06 mg/%, respectively. Studies on the content of carotenoids have shown their insignificant content in the leaves of papaya and the herb of gynostemma pentaphyllum, since these morphological groups of raw materials are not concentrators of this pigment.Conclusion. A direct correlation was established between the accumulation of iron and the content of ascorbic acid in the samples under study. The data of an experimental study indicate the promising use of the herb gynostemma pentaphyllum and leaves of papaya as sources of biologically active substances.
