Abstract:
OBJECTIVETo investigate the constituents of Elsholtzia blanda.
METHODThe chemical components were isolated by polyamide and silica gel column chromatography. Their structures were identified with extensive spectral (EI-MS, ESI-MS, 1H-NMR, 13C-NMR, DEPT, 1H-1H-COSY, HMBC, HMQC) and chemical methods.
RESULTFive compounds were isolated and identified as luteolin (I), luteolin-5-O-beta-D-glucopyranoside (II), luteolin-7-O-beta-D-glucopyranoside (III), 5-hydroxy-7, 8 -dimethoxyflavone (IV) and 5-hydroxy-6, 7-dimethoxyflavone (V).
CONCLUSIONCompounds III, IV, V were isolated from E. blanda for the first time and I was firstly separated from the genus Elsholtzia.
