摘要
目的:研究樟科山胡椒属植物乌药叶的化学成分。方法:利用硅胶柱和ODS反相柱色谱分离纯化,根据化合物的理化性质和波谱数据(1H-NMR1,3C-NMR)鉴定结构。结果:从乌药叶中分离得到8个黄酮类化合物,分别为:槲皮素-3-O-L-鼠李糖苷(1)、山奈酚-3-O-L-鼠李糖苷(2)、山奈酚(3)、二氢山奈酚-3-O-L-鼠李糖苷(4)、槲皮素(5)、槲皮素-3-O-α-D-呋喃阿拉伯糖苷(6)、槲皮素-3-O-α-D-吡喃葡萄糖苷(7)、山奈酚-3-O-D-吡喃葡萄糖苷(8)。结论:化合物2、4和8均为首次从该植物中分离得到。
Objective:To investigate the chemical constituents in the leaves of Lindera aggregate. Methods:Compounds were separated by column chromatography with silica gel and ODS. The structures were identified by physicochemical properties and spectral analysis ( ^1H-NMR, ^13 C-NMR). Results : Eight compounds were isolated and identified as : quercetin-3-O-L-rhamnoside ( 1 ), kaempferol- 3 -O-L-rhamnoside ( 2 ), kaempferol ( 3 ), dihydrokaempferol-3-O-L-rhamnoside ( 4 ) , quercetin ( 5 ), quercetin-3 -O-α-D-arabinofuranoside (6), quercetin-3-O-α-D-glucopyranoside (7), kaempferol-3-O-D-glucopyranoside (8). Conclusion : Compounds 2,4 and 8 are obtained from Lindera aggregata for the first time.
