From flower-buds of Panax ginseng C. A. MEYER cultivated in Jilin, China, ginsenosides-Ro (=chikusetsusaponin V, 9), -Rb1(1), -Rb2(2), -Rb3(10), -Rc(3), -Rd(4) and -Re(5), 20-gluco-ginsenoside-Rf(11) and ginsenosides-Rf(12), -Rg1(6) and -Rg2(13) were isolated and identified. All of these saponins have previously been isolated from ginseng roots, but the saponins 9-13 have not been isolated from flower-buds cultivated at Daikon-jima, Japan. The isolation of these pharmacologically active saponins in relatively high yields is significant in relation to the utility of the flower-buds produced at Jilin as a medicinal resource.
