中文摘要	目的研究刺桐E ry thrina varieg a ta茎皮的化学成分。方法采用硅胶、Sephadex LH-20柱色谱分离化合物,运用波谱技术分析确定化学结构。结果从刺桐茎皮65%乙醇提取物的醋酸乙酯萃取层中分离得到9个化合物,利用理化性质及波谱分析确定其结构分别为:5,4′-二羟基-8-(3,3-二甲基烯丙基)-2,″2″-二甲基吡喃[5,6∶6,7]异黄酮(Ⅰ)、豆甾醇(Ⅱ)、erythrinas inate B(Ⅲ)、3-羟基-2,′2′-二甲基吡喃[5,6∶9,10]紫檀烷(Ⅳ)、5,7-二羟基-8-(3,3-二甲基烯丙基)-二氢黄酮(Ⅴ)、5,4′-二羟基-2,″2″-二甲基吡喃[5,6∶6,7]异黄酮(Ⅵ)、5,7,4′-三羟基-6,8-二(3,3-二甲基烯丙基)异黄酮(Ⅶ)、5,2,′4′-三羟基-8-(3,3-二甲基烯丙基)-2,″2″-二甲基吡喃[5,6∶6,7]异黄酮(Ⅷ)、5,4′-二羟基-6-(3,3-二甲基烯丙基)-2,″2″-二甲基吡喃[5,6∶7,8]异黄酮(Ⅸ)。结论化合物Ⅰ、Ⅲ、Ⅳ、Ⅶ、Ⅸ为首次从该植物中分离得到,化合物Ⅴ为首次从该属植物中分离得到。; Objective To study the effective constituents from the stem bark of Erythrina variegata.Methods The compounds Ⅰ-Ⅸ were isolated by a combination of silica gel,Sephadex LH-20,and ODS chromatographies and their structures were identified by spectral methods.Results Nine known compounds were isolated from the stem bark of E.variegata.Their structures were identified by means of spectroscopic analysis as: 5,4′-dihydroxy-8-(3,3-dimethylally)-2″,2″-dimethylpyrano [5,6∶6,7] isoflavone(Ⅰ),stigmasterol(Ⅱ), erythrinasinate B(Ⅲ),3-hydroxy-2′,2′-dimethylpyrano [5,6∶9,10] pterocarpan(Ⅳ),5,7-dihydroxy-8-(3,3-dimethylally)-dihydroflavanone (Ⅴ),5,4′-dihydroxy-2″,2″-dimethylpyrano [5,6∶6,7] isoflavone(Ⅵ),5,7,4′-trihydroxy-6,8-di(3,3-dimethylally) isoflavone(Ⅶ),5,2′,4′-trihydroxy-8-(3,3-dimethylally)-2″,2″-dimethylpyrano [5,6∶6,7] isoflavone(Ⅷ),5,4′-dihydroxy-6-(3,3-dimethylally)-2″,2″-dimethylpyrano [5,6∶7,8] isoflavone(Ⅸ).Conclusion Compounds Ⅰ,Ⅲ,Ⅳ,Ⅶ,and Ⅸ are isolated from this plant for the first time and compound Ⅴ is newly isolated from the plant of Erythrina Linn.
