STUDY OF SAPONINS IN ROOTS OF ACHYRANTHES BIDENTATA BLUME
To study saponins from the roots of Achyranthes bidentata Blume (Amaranthaceae) were collected in Vietnam. Achyranthes bidentata is a tropical plant in the Amaranthaceae family, which is the most popularmedicinal plant in Asia. A complex of biologically active substances (BAS) was found in the roots of Achyranthes bidentata Blume that included saponins, ecdysteroids, polysaccharides, alkaloids, and coumarins. In this study, qualitative and quantitative analysis of saponins of Achyranthes roots was carried out. As a result of the studies, it was found that the roots contain at least three saponins predominantly triterpene group, which are derivatives of oleanolic acid. By spectrophotometric analysis of productsobtained as a result of the reaction of saponins with concentrated sulfuric acid, the quantity of the content of saponins was defined, equivalent to oleanolic acid is equaled 2,76±0,04%.
