Abstract

The rapid and highly separative ultra high-performance liquid chromatography (UHPLC)-UV method was adopted and validated to investigate the flavonol glycoside compositions in ginkgo leaf products on the Japanese market. The result indicates that certain products contained amounts of flavonol glycosides approximately equivalent to the medicinal product. Additionally, we examined the correlations between the total amount of flavonol glycosides and of terpene lactones in various ginkgo leaf products.
