| Abstract
|
| [Objective] To study the chemical component of Scorzonera mongolica Maxim.[Methods] The chemical compounds were isolated through ODS, sephadex LH-20, silicagel column chromatorgraphies and PHPLC chromatorgraphy and identified by chemical and spectral analysis.[Results] Nineteen monomeric compounds were isolated and identified from the 95% ethanol extract of Scorzonera mongolica Maxim.:3-O-ferulylquinic acid methyl ester (1), 3-O-ferulylquinic acid (2), 4-O-ferulylquinic acid (3), dihydrocaffeic acid (4), dihydrocaffeic acid n-butyl ester (5), dihydrocaffeoy acid ethyl ester (6), dihydrocaffeic acid methyl ester (7), caffeic acid (8), 3,5-dimethoxy-4-hydroxy benzoic acid ethyl ester (9), vanillin (10), 1'-O-vanillinacyl-β-D-glycosidase(11),5,7-dihydroxy-2-(4-hydroxyphenyl)-4H-1-benzopyran-4-one(12), 2-(3, 4-dihydroxyphenyl)-5, 7-dihydroxy-chromen-4-one(13), 3β-hydroxyl-5α, 8α-epidioxyergosta-6, 22-diene (14), β-sitosterol (15), β-daucosterol (16), 1-linoleic acid monoglyceride (17), linolenic acid (18), palmitic acid (19).[Conclusion] Compounds 1~3 were isolated from the plant for the first time. |
