Abstract
We have compared the panaxadiol and panaxatriol contents of white ginsengs from different countries and red ginseng, by using gas and high-pressure liquid chromatographies. Oleanolic acid contents in various ginseng species were compared by gas liquid chromatography and densitometry. Korean ginseng was found to contain greater amount of panaxadiol and panaxatriol than those of any other countries. The ginsengs from other countries, especially Chikusetzu ginseng, were found to contain far greater amount of oleanolic acid than Korean ginseng.
