灰枝紫菀化学成分的研究

Studies on the Chemical Constituents of Aster poliothamnus Diels

从灰枝紫菀全草中分得７个化合物，它们的结构经波谱方法确定为β谷甾醇，β香树素，胡萝卜甙，菠甾醇，豆甾烷醇，３β羟基２０，２４二烯达玛烷，以及用晶体衍射确定了表木栓醇的结构。除菠甾醇外，均为首次从该植物中分得。

Seven compounds were isolated from Aster poliothamnus . By means of spectral evidences and crystal analysis, their structures were elucidated as β sitosterol, β amyrin, daucosterol, spinasterol, stigmasterol, dammara 20, 24 dien 3β ol and epifriedlinol.
