Studies on Chemical Components in the Korean Panax Ginseng (1). Identification and Quantitative Determination of -Sitosterol in Crude Sterol Fraction of the Panax Ginseng

[摘要] A experiment was performed to investigate the stigmasterol and campesterol in the Panax ginseng. Crude sterol fraction obtained from the ginseng was analysed by TLC and quantitative determination of ¥â-sitosterol was performed with colorimetric method. The results were summarized as follower,1. It was observed with ethyl ether-petroleum ether extract of the ginseng that there was no evidence of showing the presence of both free campesterol and stigmasterol but that only ¥â-sitosterol was presence in a significant amount. 2. Average amount of the ¥â-sitosterol was 0.20-0.35mg per gram of the sample.
