摘    要:岩芋属Remusatia(Araceae)是一个特征鲜明的属,共含三种,即R.vivipara(Lo-dd.)Schott,R.hookeriana Schott,R.ornata(Schott)H.Li et Q.F.Guo。Go-natanthus(?)ornatus Schott中的(?)这类植物转入Remusatia属,其名应为秀丽岩芋Remusatia ornata(Schott)H.Li et Q.F.Guo.Gonatanthus ornatus 的模式标本是Hooker f.s.n.采自印度喀西山,现只有Schott绘制的模式图照片; Schlagintweit n.313,亦采自喀西山,是Krause(1920)补充描述本种的重要凭证标本,现只有遗图。R.hooke-riana Schott(1857)的模式标本Hooker f.s.n.产锡金,Krause(1920)发表的图和描述的大部分可作为该种的凭证,是一个不同于R.ornata的好种。Rao et Verma(1968)描述的 Gonatanthus ornatus应是Remusatia hookeriana.

Abstract:Besides a series of normal C21 steroids from Marsdenia incisa incisa P. T. Li et Y.P.Li,a small amount of novel C21 steroidal glycoside(II) had been isolated. The mild acidic hydrolysis of (II) afforded genin-(I).By spectroscopic analyses of IR,EIMS,FDMS,1H NMR,13C NMR (DEPT, PRFT),1H-1H COSY,1H-13CCOSY  for(I)and(II),(I)had been deduced as B-nor(7)-6β-formyl-pregnane-3β,5β,8β,12β,14β, 17β,20-heptatol,named neomarinogenin;(II)had been deduced as neomarinogenin 3-O- β-D-thevetopyranosyl- (1→4)- β-D- cymaropyranosyl-(1→4)-β-D-cymaropyranoside,named neomarinoside.Their physical and spectral data were as follows.
Keywords:Ligusticum pteridophyllum
