Abstract
A TLC scanning method for the determination of flavonol glycosides in the leaf of Ginkgo biloba has been established. The method includes hydrolysis of the flavonoids and subsequent quantitative TLC scanning assay of the aglycones obtained. Determinations were carried out with a Shimadzu CS-930 scanner, with lambda(S) = 370 nm and lambda(R) = 650 nm. The recoveries were 96.0%-99.6% with RSD of 1.03%-2.08%.
摘要
建立了一种用薄层色谱扫描法测定银杏叶中黄酮醇苷的方法。该方法包括黄酮类化合物的水解以及随后对所得苷元进行的定量薄层色谱扫描测定。测定使用岛津CS - 930扫描仪进行，λ(S)= 370 nm，λ(R)= 650 nm。回收率为96.0% - 99.6%，相对标准偏差为1.03% - 2.08%。
