Abstract:
OBJECTIVETo examine the saponins constituents in roots of Panax quinquefolium cultivated in China.
METHODThe methanol extract from roots of P. quinquefolium cultivated in Jiling province of China was extracted by chloroform and n-butanol successively. Ten pure saponins were isolated from the n-butanol extract by silica gel and RP-8 reversed-phase column chromatography. Their structures were identified by means of spectral methods and compared with known compounds.
RESULTTen saponins were isolated from P. quinquefolium. They were identified as ginsenoside Rg1(2), Re(5), Rd(7), Rc(8), Rb1(9), Rb2(10), 24(R)-ginsenoside Rg3(3), 24(R)-pseudoginsenoside RT5(1), F11(4) and notoginsenoside K(6), respectively.
CONCLUSIONThis work has elucidated the saponins constituents of P. quinquefolium cultivated in Jilin province of China and has shown that compound 1 was isolated from this plant for the first time.
