摘　　要：从暗紫贝母(Fritillaria unibracteata Hsiao et K C Hsia)的干燥鳞茎分离到化合物晶C,经光谱方法鉴定为D/E cis(22R,25S)-20-deoxy-3β-hydroxyl-6-carbonyl-5α,14α,17β-cevanine,属本属植物特征性成分异甾体生物碱,亦为新的瑟文类(cevine group)成分,命名为松贝乙素(songbeinone)。A compound C was isolated from the dry bulbs of Fririllaria unibracteata Hsiao et K.C. Hsia which belongs to a main resource species of traditional Chinese drug 'Chuan Bei-mu' in Chinese Pharmacopoeia (1990 ed.).It was identified as D/E cis(22R,25S)-20-deoxy-3β-hydroxyl -6-carbonyl-5α,14α,17β-cevanine by means of spectroscopic methods.It is a new alkaloid of 5α-cevanine group of isosteroidal alkaloids being attributed to the characteristic constituents of this genus,named as songbeinone.
