摘要
从小叶地不容(Steghania succitera Lo.et Tsoong)的块根中分得11种生物碱,根据理化性质及波谱测定,鉴定为克班宁(crebanine)(Ⅰ),四氢巴马汀(tetrahydropalmatine)(Ⅱ),去氢克班宁(dehydrocrebanine)(Ⅲ),巴马汀(palmatine)(Ⅳ),去氢紫堇单酚碱(dehydro-corydalmiae)(Ⅴ),克班宁硝酸盐(Ⅵ),氧代克班宁(oxocrebanine)(Ⅶ),紫堇单酚碱(corydalmine)(Ⅷ),phanostenine(Ⅸ),离木明碱 discretamine(Ⅹ),及 corypalmine(Ⅺ),化合物(Ⅳ)、(Ⅴ)、(Ⅵ)、(Ⅶ)、(Ⅸ)、(Ⅹ)和Ⅺ为首次报道从该植物中分得。
Eleven alkaloids were isolated from roots of Stephania succiFera Lo et Tsoong.They were identified as crebanine (Ⅰ),tetrahydropalmatine(Ⅱ),dehydrocrebanine(Ⅲ),palmatine(Ⅳ). dehydrocorydalmine(Ⅴ),crebanine nitrate(Ⅵ),oxocrebanine(Ⅶ),corydalmine(Ⅷ), phanostenine(Ⅸ),discretamine(Ⅹ)and corypalmine(Ⅺ)by means of TLC.UV,NMR MS spectral analyses and the fact that no depression of MP.with authentic samples was observed. Compounds Ⅳ,Ⅴ,Ⅵ,Ⅶ,Ⅸ,Ⅹ and Ⅺ were first reported from this plant.
