摘要
从催吐萝芙木根的乙醇提取物中分离得到15个吲哚生物碱,利用波谱(ESI—MS,^1H NMR,^13C NMR)等技术分别鉴定为利血平(1),四氢鸭脚木碱(2),异山德维辛碱(3),利血平酸甲酯(4),萝芙木碱(5),山德维辛碱(6),异育亨宾(7),霹雳萝芙木碱(8),α-育亨宾(9),育亨宾(10),催吐萝芙木定(11),四叶萝芙新碱(12),harman(13),mauiensine(14),12-hydroxymauiensine(15)。其中化合物13—15是首次从该植物中分离到。
Fifteen indole alkaloids were isolated from the roots of Rauwolfia vomitoria. On the basis of spectroscopic evidence,their structures were identified as reserpine ( 1 ), tetrahydroalstonine ( 2 ), isosandwicine ( 3 ), methyl reserpate (4), ajmaline (5) , sandwicine (6), isorauhimbine ( 7 ), perakine ( 8 ), α-yohimbine ( 9 ), yohimbine ( 10 ) , mitofidine ( 11 ), tetraphyllicine ( 12), harman ( 13 ), mauiensine (14) , and 12-hydroxymauiensine (15). Compounds 13 ~ 15 were isolated from this plant for the first time.
