title: A new diterpenoid from Fritillaria anhuiensis.
abstract: The aim of this study was to look for the chemical constituents of the bulbs of Fritillaria anhuiensis S. C. Chen et S. E. Yin. The bulbs of Fritillaria anhuiensis were extracted with 95% EtOH at reflux. Isolation and purification were performed by silica gel column chromatography. Structures of pure compounds were established on the basis of spectral analysis. Three compounds were obtained and identified as 12,15-epoxy-8(17), 13-labdadien-19-ol (1), ent-3beta-acetoxy-kauran-16beta, 17-diol (2), ent-kaurane-3beta, 16beta, 17-triol (3). Compound 1 is a new labdane-type diterpenoid. Compounds 2 and 3 were obtained from Fritillaria anhuiensis for the first time.
