摘要
为研究漆树(Toxicodendron vernicifluum)叶中的化学成分,利用硅胶柱色谱、C18中压柱色谱、高压制备色谱对漆树叶乙醇提取物的乙酸乙酯萃取部位进行分离纯化,根据化合物的波谱数据鉴定其结构.从中分离出8个化合物,分别鉴定为:没食子酸(1)、1,3,6-O-三没食子酰葡萄糖(2)、 1,2,4,6-O-四没食子酰葡萄糖(3)、紫云英苷(4)、1,2,3,4,6-O-五没食子酰葡萄糖(5)、β-谷甾醇(6)、莽草酸(7)、黄杞苷(8).其中,化合物2、3、4、7、8是首次从该种植物中分离得到,化合物1、5、6为首次从该植物的叶中分离得到.
In order to study the chemical constituents of Toxicodendron vernicifluum leaves, silica gel column chromatography, C18 medium pressure column chromatography and high pressure preparative chromatography were used to separate and purify the ethyl acetate portion of the ethanol extract from Toxicodendron vernicifluum leaves, and the structures of the compounds were identified by spectrum data. Eight compounds were isolated and identified as: gallic acid(1),1,3,6-tri-O-galloyl-β-D-glucose(2),1,2,4,6-tetra-O-galloyl-β-D-glucose(3),astragalin(4), 1,2,3,4,6-penta-O-galloyl-β-D-glucose(5),β-sitosterol(6),shikimic acid(7),engeletin(8). Among them, compounds 2, 3, 4, 7 and 8 were isolated from this plant for the first time, and compounds 1, 5 and 6 were isolated from the leaves of the plant for the first time.
