Abstract

The rise of total lipid, triglyceride and total cholesterol, and the drop of cortisol in serum induced by PA can be significantly inhibited by total ginsenosides in the leaves of Panax ginseng [GSL, 60 mg/(kg.d)]. From GSL ten compounds have been isolated and identified as ginsenoside-Rb2, -Rc, -Rd, -Re, -Rg1 -F3, F2, -Rg2, 20(R)-Rg2 and -Rh1, respectively. Pharmacological study has proved ginsenoside-Re to be the chief active constituent of GSL.

Abstract

Five compounds were isolated from the leaves of Panax ginseng and characterized as 20(R)-protopanaxatriol, daucosterine, ginsenoside-F2, ginsenoside-F3 and majoroside-F4 on the basis of spectral analysis and chemical evidence. Among them, majoroside-F4 is obtained from plant for the first time.

Abstract

Rise of total lipid, total cholesterol and triglyceride in rabbits were markedly inhibited by oral administration of ginsenosides from stems and leaves at a daily dose of 60mg/kg. The inhibitory rates were 66.2%, 92.8% and 58.1% respectively.
