苦绳的甾体成分

STUDIES ON THE CHEMICAL CONSTITUENTS OF DREGEA SINENSIS HEMSL

    摘要
  • 摘要: 从苦绳(Dregea sinensis Hemsl.)中分离到两个新化合物∶苦绳甙元乙(dresigeninB,1)和苦绳甙I(dresiosideI,2)。经光谱和化学反应确定其结构为∶20-O-(2-甲基丁酰基)托曼托甙元20-O-(2-methylbutyryl)-tomentogenin和二氢肉珊瑚甙元3-O-β-D-吡喃黄夹糖基(1-4)-β-D-吡喃夹竹桃糖基(1-4)-β-D-吡喃磁麻糖甙dihydrosarcostin 3-O-β-D-thevetopyranosyl(1-4)-β-D-oleandropyranosyl(1-4)-β-D-cymaropyranoside。

     

    Abstract: Two new compounds named dresigenin B and dresioside I were isolated from the root of Dregea sinensis Hemsl. Their structures were demonstrated as 20-O-(2-methylbutyryl) tomentogenin and dihydrosarcostin 3-O-β-D-thevetopyranosyl (1-4)-β-D-oleandropyranosyl (1-4)-β-D-cymaropyranoside by spectral evidence.
