Composition Analysis of Ginsenoside from Different Fractions of Ginseng / 世界科学技术-中医药现代化

ABSTRACT

This study was aimed to measure the content of ginsenoside in ginseng extract by UV/HPLC. Through the approximate translation comparison of two different testing results with UV and HPLC in current market, and several typical HPLC peaks ratio analysis on contents of different ginsenoside extracted from the root, stem and leaves of ginseng, in order to establish identification method of ginsenoside from different sources. The results showed that the ratio for ReRb1RcRd in ginseng root extract was approximately 12.200.940.97. And the ratio for ReRb1RcRd in ginseng leave extract was approximately 1(0.05~0.07)(0.10~0.16)(0.32~0.37). Compared with the mixture of ginseng root and ginseng leave extract, the theoretical value of ReRb1RcRd should between those two ratios. It was concluded that this method was simple, stable and reliable, which can be used as the identification method of ginsenoside from ginseng root, stem and leaves.
