伊贝碱甙A的分离和鉴定

ISOLATION AND IDENTIFICATION OF YIBEINOSIDE A

伊贝母Fritillaria pallidiflora Schreb系百合科贝母属伊贝母的干燥鳞茎,是药用贝母之一,已列入中华人民共和国1985年版药典。主产于新疆,具有产量高、生物碱含量高和抗病虫害能力强等优点。中国农科院左家特产研究所于1985年在吉林省引种栽培伊贝母获得成功。为阐明吉林省栽培的伊贝母的有效成分,以便扩大栽培和应用,我们研究了伊贝母的生物碱成分,曾分离到西贝素、西贝素-3β-D-葡萄糖甙和贝母辛。在继续研究中。

Two steroidal alkaloids were isolated from the bulb of Fritillaria pallidiflora Schreb by column chromatographic techniques. One of them was identified as known alkaloid sinpeinine A, another alkaloid was found to be a new compound named yibeinoside A, which is the Sinpeinine-3-O-β-glucoside. Its structure was confirmed on the basis of chemical and spectral data (IR, MS, ~1HNMR, ^(13)CNMR).
