鼓槌石斛化学成分的研究

STUDIES ON CHEMICAL CONSTITUENTS OF DENDROBINM CHRYSOTOSXUM LINDL.

摘要: 自中药鼓槌石斛(Dendrobium chrysotoxum Lindl.)茎中分离到5个化合物,经光谱(UV,IR,MS,¹HNMR,DIFNOE和¹³CNMR)分析,分别鉴定为β-谷甾醇(I)、鼓槌菲(chrysotoxene,II)、毛兰素(erianin,III)、毛兰菲(confusarin,IV)和鼓槌联苄(chrysotobibenzyl,V)。II是新化合物,V是新天然产物。

Abstract: Five compounds were isolated from stems of Dendrobium chrysotoxum Lindl..On thebasis of spectral(UV,IR, EI-MS, ¹HNMR ,DIFNOE,¹³CNMR ) analysis ,they were identified asβ-sitosterol(I),2-hydroxy-1,5,6,7-tetramethoxyphenanthrene(II),erianin(III),confusarin(IV)and 3,4,5,3'4'-pentamethoxybibenzyl(V).II is a new compound named chrysotoxene,V isa new natural product named chrysotobibenzyl.
