摘要: 采用硅胶柱色谱分离技术,结合TLC、紫外光谱、NMR、MS等方法对荷包地不容(Stephania.dicentrinifera H.S.Lo& M.Yang)中生物碱成分进行研究。采用小鼠尾静脉注射法进行同亚属植物中所得三种阿朴菲类(Aporphine,AP)生物碱的急性毒性试验,用Bliss法计算半数致死量(LD50)并比较几种AP类生物碱的毒性与结构的关系。结果分离和鉴定了3个生物碱成分,分别为AP型的荷包牡丹酮(Dicentrinone,Dico)和荷包牡丹碱(Dicentrine,Dic),以及原小檗碱(Protoberberine,PBB)型的四氢巴马汀(Tetrahydropalmatine,Tet)。其中Dico为首次从荷包地不容中分离出来,其LD50=7.266 mg/kg ,Dic的 LD50=26.802 mg/kg,异可利定(Isocorydine,Isoc)的 LD50=32.167 mg/kg。

Abstract: In this study,aporphine(AP)-type alkaloids were isolated from Stephania dicentrinifera H.S.Lo & M.Yang by silica gel column chromatography.Their structures were identified by TLC,UV,NMR,MS, etc.The acute toxicity of 3 obtained alkaloids [Dicentrinone(Dico)and Dicentrine(Dic)of AP-type alkaloids, Tetrahydropalmatine(Tet) of Protoberberine(PBB)-type alkaloids] was then investigated using the method of tail vein injection in mice,their LD50's were calculated by Bliss method.The experimental results showed that the LD50 values of Dico,Dic and Isocorydine(Isoc)were 7.266 mg/kg,26.802 mg/kg and 32.167 mg/kg,respectively.Dico was separated from S.dicentrinifera for the first time,and its acute toxicity was higher than Dic and Isoc.

Key words: Stephania.dicentrinifera H.S.Lo &, M.Yang;aporphine alkaloids;dicentrinone;dicentrine;isocorydine;LD50
