| Abstract
|
| [Objective] To investigate chemical constituents from the leave of Epimedium brevicornu Maxim.[Methods] The compounds were purified by solvents extracting and several column chromatography, including silica gel, Sephadex LH-20, ODS and preparative HPLC.Their structures were identified by MS and NMR spectra.[Results] Seven compounds were separated from 95% ethanol(V/V) extract of E.brevicornu and identified as 2, 3, 5, 6, 7-pentamethoxy-phenanthrene(1), 4, 5-dihydroxy-2, 3, 6-trimethoxy-9, 10-dihydrophenanthrene(2), 5, 7, 4'-trimethoxy-4-phenylcoumarin(3), 3, 5, 7, 4'-tetramethoxyflavone(4), 4-hydroxy-3-prenylbenzoic acid(5), 4-Hydroxycinnamic acid methyl ester(6), and(2E)-2-nonenoic acid, 4-hydroxy(7).[Conclusion] Compound 1~7 were obtained from genus of Epimedium for the first time. |
