Abstract:
OBJECTIVETo study flavonoids in Scutellaria barbata and elucidate their structures.
METHODCompounds were isolated and purified by normal column chromatography, paper thin layer chromatography and Sephadex chromatography. The chemical structures were elucidated by ESI mass and NMR spectra.
RESULTFive flavonoids were isolated from S. barbata and identified as apigenin (1), luteolin (2), ethyl-7-O-apigenin-glucuronate (3), apigenin-7-O-beta-glucoside (4), and apigenin-7-O-neohesperidoside (5), in addition to benzyaldehyde (6).
CONCLUSIONFlavonoidglycoside (3), (4) and (5) were isolated from S. barbata for the first time.
