摘　　要：从苍白秤钩风（Ｄｉｐｌｏｃｌｉｓｉａｇｌａｕｃｅｓｅｎｓ）的茎干中分离到１个炔酸，９－炔－十八酸，其结构通过波谱和化学的方法得到鉴定。经筛选具有ＰＡＩ－１活性。同时还得到三十碳酸，十一碳酸和β－谷甾醇。A acetylenic acid, ocetadecanoic acid-9-yne has been isolated from the stem of Diploclisia glaucescens . Its structure was elucidated by spectral method and chemical reaction. In addition, triacontanoic acid, undecanoic acid and β-sitosterol were also obtained. One of them, ocetadecanoic acid-9-yne was isolated from D glaucescens for the first time. It shows stronger PAI-1 bioactivity.
