摘要
在高效硅胶薄层板上以石油醚－乙醚－甲酸－乙酸乙酯的上层（展开剂Ⅰ），分离槲皮素、山奈素和异鼠李素；扫描测定后再次展开，以氯仿－甲醇－水的下层－乙酸（展开剂Ⅱ），分离槲皮甙、异鼠李甙．用日本岛津ＣＳ－９０００型双波长薄层扫描仪进行直线扫描，在波长为３７０ｎｍｎ处测定了银杏叶５种黄酮成分的含量．
With the upper layer of petroleum ether-ether-formic acid-acetic ester(60:30:6:4)(developing solvent I),quercetrin,kaempferol and isorhamnetin were developed on high-performance thinulayer plate of silica,and scanned.Then,quercitin and isorhamnoside were separated with the lower layer of chloroform-methanol-water(6:4:2)and acetic acid(15:1)(developing solvent Ⅱ).The detection was carried out with linear scanning at 370 um by a CS-9000 dual-wavelength thin-layer scanner(Shimadzu,Japan).The contents of 5 kinds of flavones and flavones glycosides were determined in ginkgo biloba leave extracts.
