[Isolation and indentification of chemical compounds from Drynaria fortunei]
1Beijing Institute of Pharmacology and Toxicology, Academy of Military Medical, Sciences, Beijing 100852, China.
Objective:
To study the chemical components of Drynaria fortunei.
Method:
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.
Result:
Four compounds were isolated, three of which were identified as (-)-epiafzelechin-3-O-beta-D-allopyranoside, (-)-epiafzelechin and beta-sitosterol.
Conclusion:
(-)-epiafzelechin-3-O-beta-D-allopyranoside, (-)-epiafzelechin were obtained from D. fortunei for the first time.
