Abstract

OBJECTIVE To study the chemical constituents of Dryopteris crassirhizoma.METHODS The column chromatography of silica gel and sephadex were used to isolate those constituents.IR, 1H-NMR and MS were used to identify the compounds.RESULTS Six compounds were obtained and identified as hexacosanic acid(Ⅰ),pentacosanol(Ⅱ),nerolidol(Ⅲ),dryocrassin ABBA(Ⅳ),flavaspidic acid AB(Ⅴ) and (Ⅵ).CONCLUSION The compounds Ⅰ,Ⅱ,Ⅲ and Ⅵ were isolated from Dryopterisgenus for the first time.The compound Ⅴ was isolated from Dryopteris crassirhizoma for the first time.
