    Chemical constituents from roots and rhizomes of Panax ginseng cultivated in Jilin province.[Pubmed: 24380303]

    METHODS AND RESULTS:
    The chemical constituents of the roots and rhizomes of Panax ginseng were systematically investigated by various column chromatographic methods including Amberlite XAD-4 macroporous adsorptive resins and silica gel as well as high-performance liquid chromatography, and their chemical structures were identified by physico-chemical properties and spectral analyses. Twenty-eight compounds were isolated from the 70% ethanolic-aqueous extract and identified as koryoginsenoside R1 (1), ginsenoside Rg1 (2), ginsenoside Rf (3), notoginsenoside R2 (4), ginsenoside Rg2 (5), notoginsenoside Fe (6), ginsenjilinol (7), ginsenoside Re5 (8), noto-ginsenoside N (9), notoginsenoside R1 (10), ginsenoside Re2 (11), ginsenoside Re1 (12), ginsenoside Re (13), ginsenoside Rs2 (14), ginsenoside Ro methyl ester (15), ginsenoside Rd (16), ginsenoside Re3 (17), ginsenoside Re4 (18), 20-gluco-ginsenoside Rf (19), ginsenoside Ro (20), ginsenoside Rc (21), quinquenoside-R1 (22), Ginsenoside Ra2 (23), ginsenoside Rb1 (24), ginsenoside Ra1 (25), ginsenoside Ra3 (26), ginsenoside Rb2 (27), and notoginsenoside R4 (28). All isolated compounds are 20 (S) -protopanaxadiol or protopanaxatriol type triterpenoid saponins. Compound 1 was isolated from the roots and rhizomes of P. ginseng cultivated in Jilin province for the first time and compound 6 was isolated from the roots and rhizomes of P. ginseng for the first time.
    CONCLUSIONS:
    The 1H-NMR data of compounds 6, 14 and 19 were assigned for the first time.
