Ginsenoside Rf is a ginsenoside found in Panax ginseng and Panax japonicus var. major that is dammarane which is substituted by hydroxy groups at the 3beta, 6alpha, 12beta and 20 pro-S positions, in which the hydroxy group at position 6 has been converted to the corresponding beta-D-glucopyranosyl-(1->2)-beta-D-glucopyranoside, and in which a double bond has been introduced at the 24-25 position.
A ginsenoside pharmaceutical composition having tyrosinase inhibitory activity and use thereof
The present application relates to a ginsenoside composition for inhibiting tyrosinase activity, which comprises any two or any three of ginsenoside Rd, ginsenoside Re or ginsenoside Rf. Ginsenoside Rf can be used as a synergistic molecule of ginsenoside Rd and Re, and can significantly enhance the inhibitory ability of tyrosinase activity through synergistic effect, thereby reducing the synthesis and secretion of melanin.

An optimal method for extracting Panax notoginseng saponins using solvents of different polarities, based on high-performance liquid chromatography combined with the Kruskal-Wallis H test.
This invention belongs to the technical field of Panax notoginseng saponin extraction methods, specifically relating to an optimal method for studying the extraction of Panax notoginseng saponins using different polar solvents based on high-performance liquid chromatography (HPLC) combined with the Kruskal-Wallis H test. The method includes the following steps: S1. Preparation of test sample solution; S2. Preparation of control sample solution; S3. Component detection: HPLC is used to detect saponin components in Panax notoginseng samples; S4. Statistical analysis: The Kruskal-Wallis H nonparametric statistical test is used to perform statistical analysis of inter-group differences in the content of saponin components. This application constructs a research method combining HPLC and the Kruskal-Wallis H nonparametric statistical test, accurately distinguishing the effects of extraction of nine saponin components on their content in different organic solvents, and identifying ginsenoside Rf as a potential quality marker for distinguishing Panax notoginseng samples extracted with different polar solvents. This has significant practical implications for selecting extraction solvents for Panax notoginseng saponins and for conducting in-depth research on the effective components of Panax notoginseng.
