摘要
[目的]研究镰形棘豆（Oxytropis falcataBunge）的化学成分。[方法]应用正、反相硅胶柱色谱法进行分离纯化,根据理化性质和波谱数据鉴定化合物结构。[结果]从镰形棘豆95%乙醇提取物中分离得到了8种化合物,分别鉴定为β-谷甾醇（1）、柚皮素（2）、5,6-二羟基-2,7,3′,4′-四甲氧基黄酮醇（3）、5,6-二羟基-2,7,4′-三甲氧基黄酮醇（4）、3′,4′,5,7-四羟基双氢黄酮（5）、黄芹素（6）、7α-hydrox-ysitosterol（7）、7-oxositosterol（8）。[结论]化合物28为首次从该植物中分离得到。
[Objective] To study the chemical constituents of the whole plant of Oxytropis falcata Bunge.[Method] The chemical constituents were isolated by the column chromatography of silica gel and RP-18 gel.Their chemical structures were elucidated on the basis of physicochemical properties and spectral data analysis.[Result] 8 compounds were obtained and identified as β-sitosterol（1）,naringenin（2）,5,6-dihydroxy-3,7,3＇,4＇-tetramethoxyflavonol（3）,5,6-dihydroxy-3,7,4＇-trmiethoxyflavonol（4）,3＇,4＇,5,7-4-hydroxy-flavanone（5）,apigenin（6）,7a-hydroxysitosterol（7）,7-oxositosterol（8）.[Conclusion] Compounds 2-8 were isolated from the plant for the first time.
