Isolation and indentification of chemical compounds from Drynaria fortunei / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the chemical components of Drynaria fortunei.</p><p><b>METHOD</b>The herbal material was extracted with 75% ethanol. The chemical components were isolated by silica gel and sephadex LH-20 column chromatography. The structures were identified on the basis of chemical and spectroscopic data.</p><p><b>RESULT</b>Four compounds were isolated, three of which were identified as (-)-epiafzelechin-3-O-beta-D-allopyranoside, (-)-epiafzelechin and beta-sitosterol.</p><p><b>CONCLUSION</b>(-)-epiafzelechin-3-O-beta-D-allopyranoside, (-)-epiafzelechin were obtained from D. fortunei for the first time.</p>
