Abstract:
OBJECTIVETo isolate and determine the chemical constituents from Astilbe chinensis.
METHODFour compounds were isolated and purified by extraction and column chromatography on silica gel. The chemical structures were determined on the basis of physical-chemical evidence and extensive spectral analysis(HR-EIMS, EIMS, 13C-NMR, 1H-NMR, DEPT, 1H-1H-COSY, HMQC and HMBC).
RESULTTheir structures were elucidated as beta-sitosterol palmitate I, daucosterol II beta-sitosterol III and Bergenin IV, respectively.
CONCLUSIONCompound I and II were isolated from A. chinensis for the first time.
