Makino. The morphological and anatomical characteristics of the Gynostemma herb have been established. A quantitative assessment of diagnostically significant signs was carried out using a microscopic method. Using various analytical methods of phytochemical analysis, the quantitative content of the main groups of biological active substances was determined: tannins, ascorbic acid, free organic acids, polysaccharides, saponins and flavonoids. A high content of biologically active substances (saponins and flavonoids), which are pharmacologically active components in the herb Gynostemma pentaphyllum, was revealed. © The Authors, published by EDP Sciences.
