Abstract: To determine the chemical constituents from Sibiraea angustata(Rehd.) Hand-Mazz, its 80% ethanol extract was isolated and purified by chromatograph over silica gel, Sephadex LH-20 and HPLC, etc. Nine compounds were isolated and identified as hyperoside(Ⅰ), quercetin(Ⅱ), rutin(Ⅲ), quercetin-3-O-β-D-glucopyranoside(Ⅳ), catechin(Ⅴ), vanillic acid(Ⅵ), arbutin(Ⅶ), isoferulic acid(Ⅷ), daucosterol(Ⅸ). Their chemical structures were determined by chemical methods, NMR spectral data. Compounds Ⅰ~Ⅲ and Ⅴ~Ⅶ were isolated from the leaves of Sibiraea angustata(Rehd.) Hand-Mazz. for the first time.

Key words: Sibiraea angustata(Rehd.) Hand-Mazz., chemical constituent, flavonoids, isolation, identfication
