流苏石斛化学成分的研究（Ⅰ）

目的：从兰科植物流苏石斛（Denddrobium fimbriatum Hook.)茎中提取分离活性成分。方法：95%乙醇提取、溶剂抽提、硅胶柱层析、重结晶等。结果：分离出9个化合物，鉴定出其中6个，分别为大黄酚（3）、三十二烷酸（5）、对羟基反式肉桂酸三十烷基酯（6）、对羟基顺式肉桂酸三十烷基酯（7）、β-谷甾醇（8）和鼓槌联苄（9），结论：大黄酚为资产从石斛属植物中分得，鼓槌联苄为首次从该积木教授中分离得到。

Chemical Constituents of Dendrobium fimbriatum Hook.(

AIM　Bio-active constituents were expected to be obtained from Dendrobium fimbriatum Hook. METHODS　It was extracted with 95% alcohol, distributed by petrol, isolated via column chromatography on silica gel and purified by crystallization. RESULTS　Nine compounds were isolated from the stems of Dendrobium fimbriatum Hook., On the basis of spectral analyses, six compounds of them were identified as chrysophanol(3), n-dotriacodtanoic acid(5), defuscin(6), n-triacontyl cis-p-coumarate(7), β-sitosterol(8) and chrysotobibenzyl(9). CONCLUSION　Chrysophanol(3) was firstly isolated from Genus dendrobium and chrysotobibenzyl(9) was found from this species for the first time.
