RESUMO
OBJECTIVE: To study the chemical constituents from Evodia delavayi. METHODS: The constituents of Evodia delavayi were isolated by silica gel and Sephadex LH-20 column chromatography. RESULTS: Their structures were elucidated by anlalyzing their spectral data and compared with previously reported literatures. Thirteen compounds were identified as evodiamine (1), rutaecarpine (2), skimmiamine (3), 7β-hydroxyrutaecrpine (4), goshuyuamide 1(5), goshuyuamide II (6), negunfurol (7), schensianol(8), rutaecine(9), isorhamnetin(10), 7-ketositosterol(11), evodol(12), and β-sitosterol(13). CONCLUSION: All compounds are isolated from this plant for the first time, and compounds 7, 8, and 11 are isolated from the genus Evodia for the first time.
RESUMO
Sixteen compounds have been isolated from the EtOAc fraction of 95% ethanolic extract of Sophora dunnii through silica gel, Sephadex LH-20 and semi-prerarative HPLC column chromatographies. Their structures were identified on the basis of NMR and MS spectra data as phaseollidin (1), L-maackiain (2), 2-(2',4'-dihidroxyphenyl)-5,6-methylenedioxy benzofuran (3), 8-demethyl-farrerol (4), liquiritigenin (5), genistein (6), 6-methylgenistein (7), 5-O-methyl genistein (8), 7,2',4'-trihydroxys-5-methoxy-isoflavanone (9), 7, 3', 4'-trihydroxy-isoflavanone (10), erythribyssin D (11), calycosin (12), trans-resveratrol (13), cis-resveratrol (14), stigmasterol (15), β-sitosterol (16). Among these, compounds 1-14 and 16 were isolated from this plant for the first time.
