tentative structure (A),2 for cynanchogenin (1), an aglycone from Cynanchum caudatum Maxim. (Asclepiadaceae).3 In the same year, Cornforth gave the structure (B),4 for sarcostin (2), which is also an aglycone from an Australian plant, Sarcostemma australe.5 Abisch et al. also isolated several compounds from an African plant, Pachycarpus lineolatus, among which lineolon (-deacylcynanchogenin) (3) and sarcostin
狂犬激肽原(1)和sarcostin(2)的结构已基于

化学证据,并描述了Lineolon(-deacylcynanchogenin; 3)与常规类
固醇的相关性。在1959年,作者提出的临时结构(甲),2为cynanchogenin(1)中,从一个糖苷配基牛心万年青马克西姆。(萝cle科)。3在同一年,Cornforth给出了结构(B),为sarcostin(2)给出了结构4,这也是来自澳大利亚植物Sarcostemma australe的糖苷配基。5Abisch等。还从非洲植物Pachycarpus lineolatus中分离了几种化合物,其中主要成分是lineolon(-deacylcynanchogenin)(3)和sarcostin(2)。6从那时起,这两种化合物都已从许多植物中分离出来,并被证明是分布非常广泛的类
