摘 要: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。AIM: To investigate the chemical constituents of the seeds of M. citrifolia. METHODS: The chemical constituents from the seed of M. citrifolia were separated and purified by silica gel, Rp-18, Sephadex LH-20 column chromatography and Pre-TLC. Their structures were elucidated on the basis of extensive spectroscopic analysis (including 2D NMR). RESULTS: Twenty known compounds were identified as daucosterol (1), ursolic acid (2), 19-hydroxyl-ursolic acid (3), 1, 5, 15-trimethylmorindol (4), 5, 15-dimethyl-morindol (5), scopoletin (6), 3, 3'-bisdemethylpinoresinol (7), 3, 4, 3' 4'- tetrahydroxy-9, 7'a-epoxylignano-7a, 9'-lactone (8), americanin D (9), americanin A (10), americanin (11), isoprincepin (12), deacetyl-asperulosidic acid (13), loganic acid (14), asperulosidic acid (15), rhodolatouside (16), quercetin-3-O-a-L- rhamnopyranosyl-(1→6)-β-D-glucopyranoside (17), 4-ethyl-2-hydroxyl-succinate (18), 5-hydroxymethyl-2-furancarboxaldehyde (19), 3-methylbut-3-enyl-6-O-β-D-glucopyranosyl-fl-D-glucopyranoside (20). CONCLUSION: Compounds 9, 11, 14, 16 and 18 are reported from M. citrifolia for the first time.
