目的:研究诺丽籽化学成分。方法:利用硅胶柱层析、反相RP-18、半制备薄层层析和凝胶柱层析对诺丽籽进行分离纯化,借助光谱学手段鉴定其结构。结果:分离得到20个已知化合物:胡萝卜甾醇(1),乌苏酸(2),19-羟基-乌苏酸(3),1,5,15-trimethylmorindol(4),5,15-dimethyl-morindol(5),东莨菪亭(6),3,3’-双二甲基松脂素(7),3,4,3’4’-四羟基-9,7’α-过氧化木脂素-7α,9’-丁内酯(8),americanin D(9),americanin A(10),americanin(11),isoprincepin(12),去乙酰车叶草苷酸(13),落干酸(14),车叶草苷酸(15),rhodolatouside(16),芦丁(17),4-乙基-2羟基-丁二酸(18),5-羟甲基-2-呋喃甲醛(19),3-甲基丁基-3-烯基海藻糖(20)。结论:化合物9、11、14、16和18首次从该植物中分离得到。
Objective: To study the chemical constituents of Noni seed. Methods: Noni Seeds were isolated and purified by silica gel column chromatography, reverse phase RP-18, semi-preparative TLC and gel column chromatography. Their structures were identified by spectroscopic methods. RESULTS: Twenty known compounds were isolated: carotasterol (1), ursolic acid (2), 19-hydroxy-ursolic acid (3), 1,5,15-trimethylmorindol (4), 5,15-dimethyl -morindol (5), scopoletin (6), 3,3’-dimethyldimethylpolysin (7), 3,4,3’4’-tetrahydroxy-9,7’α- (8), americanin D (9), americanin A (10), americanin (11), isoprincepin (12), deacetyl carotenoid (13) (15), rhodolatouside (16), rutin (17), 4-ethyl-2hydroxy-succinic acid 19), 3-methylbutyl-3-alkenyltrehalose (20). Conclusion: Compounds 9, 11, 14, 16 and 18 were isolated from this plant for the first time.
