摘要
目的研究白花檵木中的化学成分。方法采用大孔树脂、C18反相、Sephadex LH-20、硅胶等材料进行柱色谱分离、提纯,并根据理化性质及波谱数据鉴定化合物结构。结果从白花檵木中分离得到11个化合物,分别鉴定为3-O-p-香豆酰奎尼酸(1)、5-O-p-香豆酰奎尼酸甲酯(2)、绿原酸甲酯(3)、没食子酸甲酯(4)、对羟基苯甲酸(5)、槲皮素-3-O-α-L-鼠李糖苷(6)、山奈酚-3-O-β-D-葡萄糖苷(7)、杨梅素-3-O-α-L-鼠李糖苷(8)、槲皮素-3-O-(6''-O-没食子酰基-β-D-葡萄糖苷)(9)、槲皮素(10)、杨梅素(11)。结论化合物1~6、9为首次从该属植物中分离得到。
Objective To study the chemical constituents of Loropetalum chinense. Methods The chemical constituents were separated and purified by macroporous resin,RP-C18,Sephadex LH-20 and silica gel column chromatography. All the compounds were identified by physico-chemical properties and spectroscopic analysis. Results Eleven compounds were isolated from L. chinense and identified as 3-O-p-coumaroylquinic acid( 1),methyl5-O-p-coumaroylquinic acid( 2),methyl chlorogenate( 3),methyl gallate( 4),p-hydroxy-benzoic acid( 5),quercetin-3-O-α-L-rhamnopyranoside( 6),kaempferol-3-O-β-D-glucopyranoside( 7),myricetin-3-O-α-L-rhamnopyranoside( 8),quercetin-3-O-( 6''-O-galloyl-β-D-glucopyranoside)( 9),quercetin( 10) and myricetin( 11). Conclusion Compounds 1,2,3,4,5,6 and 9 were isolated from this genus for the first time.
