Chen Yan, Fang Sheng-ding, Akinori Suzuki and Akira Isogai   

Abstract: 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.

Key words: Stephania succifera Tetrahydropalmatine, Crebanine: Crebanine nitrate
