鼓槌石斛化学成分的研究

Chemical Constituents of Dendrobium chrysotoxum

目的 研究鼓槌石斛的化学成分,为阐明其活性成分,开发其资源提供科学依据。方法 采用硅胶柱层析法进行分离,根据光谱数据鉴定结构。结果 从中分得4个化合物,分别为;2,4,7-三羟基-9,10-二氢菲（Ⅰ）,2,7-二羟基-3,4,6-三甲氧基菲（Ⅱ）,5,4’-二羟基-3,3’二甲氧基联苄（Ⅲ）,3,4-二径基苯甲酸（Ⅳ）。结论 化合物Ⅰ-Ⅳ均为首次从石斛属植物中分得。

AIM To study the chemical constituents of Dendrobium chrysotoxum Lindl. METHODS Compounds were separated by column chromatography on silica gel and their structures were elucidated based on chemical and spectral analyses. RESULTS Four compounds were isolated from Dendrobmm chrysutoxum and identified as 2,4,7-trihydroxy-9, 1 0-dihydrophenanthrene (Ⅰ ), 2, 7-dihydroxy- 3, 4, 6- trimethoxy- phenanthrene ( Ⅱ ) , 5, 4'-dihydroxy -3 ,3'-dimethoxydibenzyl ( Ⅲ ), 3 , 4-dihydroxybenzoic acid (Ⅳ). CONCLUSION Compounds Ⅰ-Ⅳ were obtained from (Venus Dendrobium for the first lime.
