摘  要:目的 研究滇产干花豆(Fordia cauliflora Hemsl)茎的化学成分。方法 采用反复硅胶柱色谱进行分离纯化,根据光谱数据和理化性质进行结构鉴定。结果 从干花豆乙醇提取物中分离得到6个化合物,分别鉴定为6-羟基-3-甲氧基-6″,6″-二甲基吡喃(2″,3″:7,8)黄酮(1),3-甲氧基-6-(3-甲基-2-丁烯氧基)-6″,6"-二甲基吡喃(2″,3″:7,8)黄酮(2),3,6-二甲氧基-6″,6"-二甲基吡喃(2″,3″:7,8)黄酮(3),7-羟基4’-甲氧基异黄酮(4),7,4’-二羟基异黄酮(5)和水黄皮素(6)。结论 化合物1和2为新化合物,化合物3—5为首次从该植物中分离得到。Aim To study the chemical constituents of the stem of Fordia cauliflora of Yunnan province. Methods The constituents were separated and purified by repeated silica column chromatography. The structures were elucidated by physical-chemical properties and spectroscopic data. Results Six compounds were isolated from the ethanol extract of the stem of Fordia cauliflora. They were identified as : 6-hydroxy-3-methoxy-6",6"-dimethylchromeno-(2", 3": 7,8 ) -flavone ( 1 ) , 3-methoxy-6-( 3- methyl-but-2-enyloxy)-6", 6"-dimethylchromeno-( 2", 3" : 7, 8 )-flavone ( 2 ) , 3, 6-dimethoxy-6", 6"- dimethylchromeno-(2", 3" : 7, 8 )-flavone ( 3 ), 7-hydroxy-4'-methoxyisoflavone ( 4 ), 7, 4'- dihydroxyisoflavone (5) and karanjin (6). Conclusion Compounds 1 and 2 are new compounds. Compounds 3 -5 were isolated from the plant for the first time.
