水罗伞的化学成分(Ⅲ)

Chemical constituents of Fordia cauliflora (Ⅲ)

目的 对广西壮、瑶医常用药物豆科植物水罗伞 Fordia cauliflora根的活性成分进行研究。方法 采用反复硅胶柱色谱及薄层色谱进行分离纯化 ,通过理化方法及光谱分析鉴定其结构。结果 又分离出 3个结晶性成分 ,经鉴定分别为 2 - [3-甲氧基苯基 ]- 4 H-呋喃 [2 ,3- h]- 1-苯并吡喃 - 4 -酮 ( )、3-甲氧基 - 2 - [3-羟基苯基 ]- 4 H-呋喃 [2 ,3-h]- 1-苯并吡喃 - 4 -酮 ( )和水黄皮亭 (水黄皮根素 ,pinnatin, )。结论 化合物 ～ 均为首次从该植物中分离得到 ,其中 , 为新化合物 ,分别命名为水罗伞甲素 ( cauliflorin A)和水罗伞乙素 ( cauliflorin B)。

Object To study the chemical constituents of the dried root of Fordia cauliflora Hemsl which is indigenous to Guangxi and commonly used in traditional medicine of Zhuang and Yao nationalities Methods The constituents were isolated with column chromatography and their structures were elucidated on the basis of physicochemical data and spectral analysis Results The three constituents were isolated and identified as 2 [3 methoxyphenyl] 4H furo[2,3 h] 1 benzoyran 4 one (Ⅲ), 3 methoxy 2 [3 hydroxyphenyl] 4H furo [2, 3 h] 1 benzopyran 4 one (Ⅳ) and pinnatin (Ⅴ) Conclusion The all of them are isolated from this plant for the first time Compound Ⅲ,Ⅳ are new and tentatively named as cauliflorin A and cauliflorin B
