Development and Validation of an Analytical Method for the Determination of Flavonol Glycosides in Ginkgo Leaves and ShuXueNing Injections by a Single Marker.

The qualitative and quantitative analysis of the major bioactive components in traditional Chinese medicines (TCM) and their preparations is essential to evaluate their quality. However, the scarcity and high cost of chemical reference standards are common obstacles for quantitative analysis, especially for determining multicomponents. In this study, an effective and sensitive qualitative method to identify flavonol glycosides in Ginkgo leaves (Ginkgo Folium), and their preparations have been developed.
