Studies on the chemical constituents in radix Astilbes chinensis / 中国中药杂志

<p><b>OBJECTIVE</b>To isolate and determine the chemical constituents from Astilbe chinensis.</p><p><b>METHOD</b>Four 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).</p><p><b>RESULT</b>Their structures were elucidated as beta-sitosterol palmitate I, daucosterol II beta-sitosterol III and Bergenin IV, respectively.</p><p><b>CONCLUSION</b>Compound I and II were isolated from A. chinensis for the first time.</p>
