分馏紫茎泽兰地上部分的氯仿提取物并检查生长抑制情况。植物材料的生物测定部分提供了三种已知的杜松子烯和β-谷甾醇。使用洋葱、萝卜和黄瓜种子测定了不同组分以及分离的杜松烯的影响。三天暴露于这些杜松子烯中显着抑制了所有三种测定种子的发芽和幼苗生长。抑制程度取决于种子种类和测试化合物的浓度。发现杜松烯(1)对测试的种子具有更强的抑制作用，杜松烯(3)的活性低于(1)和(4)。
Chloroform extract of the aerial parts of Eupatorium adenophorum Spreng was fractionated and examined for growth inhibition. Bioassay-directed fractions of the plant materials afforded three known cadinenes and beta-sitosterol. The effects of different fractions as well as isolated cadinenes were determined using Allium cepa, Raphanus sativus, and Cucumis sativus seeds. Three-day exposure to these cadinenes significantly inhibited germination and seedling growth of all three assay seeds. The degree of inhibition was dependent upon seed species and the concentrations of the compounds tested. Cadinene (1) was found to be more inhibitory to the seeds tested and the activity of the cadinene (3) was less than that of (1) and (4).
