摘要 目的:研究黄花紫玉盘Uvaria kurzii枝、叶的化学成分。方法:硅胶色谱柱和Sephadex LH-20分离纯化,根据理化性质和波谱数据鉴定结构。结果:分离鉴定了19个化合物,分别为β-谷甾醇十六烷酸酯(1),豆甾醇十六烷酸酯(2),β-乙酰谷甾醇(3),β-乙酰豆甾醇(4),三十四烷醇(5),三十二烷酸(6),β-谷甾醇(7),豆甾醇(8),5α-豆甾-3,6-二酮(9),5α-豆甾-22-烯-3,6-二酮(10),香草酸(11),原儿茶酸(12),N-(对-反式-香豆酰)酪胺(13),山柰酚-3-O-β-D-(6″-O-对-香豆酰)半乳吡喃糖苷(14),山柰酚-3-O-芸香糖苷(15),芦丁(16),胡萝卜苷(17),L-白雀木醇(18),尿囊素(19)。结论:化合物1~6,9,10,13,18,19为本科中首次分到;14~16为本属中首次分到;7,8,11,12,17为本种植物中首次分到。 Objective: To investigate the chemical constituents of the branches and leaves of Uvaria kurzii. Method: Compounds were isolated and purified by silica gel and Sephadex LH-20 column chromatography. Their chemical structures were identified on the basis of physicochemical properties and spectral data. Result: Nineteen compounds were isolated and identified as: β-sitosterol hexadecanoate (1), stigmasterol hexadecanoate (2), β-acetylsitosterol (3), β-acetylstigmasterol (4), tetratriacontanol (5), dotriacontanoic acid (6), β-sitosterol (7), stigmasterol (8), 5α-stigmast-3,6-dione (9), 5α-stigmast-22-ene-3,6-dione (10), vanillic acid (11), protocatechuic acid (12), N-(p-trans-coumaroyl) tyramine (13), kaempferol-3-O-β-D-(6″-O-p-coumaryoyl) galactopyrannoside (14), kaempferol-3-O-rutinoide (15), rutin (16), daucosterol (17), L-quebrachitol (18), allantoin (19), respectively. Conclusion: Compounds 1-6, 9, 10, 13, 18, 19 were isolated from Annonaceae plants; Compounds 14-16 were obtained from the genus Uvaria; and 7, 8, 11, 12, 17 were separated from this plant respectively for the first time.
