摘 要 ：目的：研究假鹰爪种子的化学成分，以寻找抗癌活性成分或新的化合物。方法：用溶剂提取和多种层析方法分离，用光谱方法鉴定化合物的结构。结果：分离并鉴定了１１个化合物，分别为ｌａｗｉｎａｌ（１），ｄｅｓｍｏｓａｌ（２），ｄｅｓｍｅｔｈｏｘｙｍａｔｅｕｃｉｎｏｌ（３），ｕｎｏｎａｌ（４），ｉｓｏｕｎｏｎａｌ（５），ｄｅｓｍｏｓｆｌａｖｏｎｅ（６），尿囊酸（７），琥珀酸（８），胡萝卜甙（９），β 谷甾醇（１０）和硬脂酸（１１）。通过１ＨＮＭＲ ＮＯＥ差谱技术对１和２的结构重新进行了研究，证明１和２互为异构体。结论：化合物２是新的天然产物，７，８和９系首次从该植物中分得。

Abstract:Objective: To investigate the chemical constituents of Desmos chinensis. Method: Various column chromatographic techniques were employed for the isolation and purification of constituents from the ethanol extract.The structures were elucidated by spectral analysis. Result: Eleven compounds were isolated and identified as lawinal(1),desmosal(2),desmethoxymatteucinol(3),unonal(4),isounonal(5),desmosflavone(6),alla ntoic acid(7),succinic acid(8),daucosterol(9),sitosterol(10)and stearic acid(11).The structures of compounds 1 and 2 were reconfirmed by NOEDS technique. Conclusion: Compound 2 is a new natural product and 7,8 and 9 were found from this plant for the first time.
