What is SOP for Quercetin Analysis in Ginkgo about?

This standard operating protocol describes the determination of flavonol glycosides in Ginkgo biloba products by HPLC analysis. The method involves extracting plant materials or dried extracts with ethanol and water, then hydrolyzing the glycosides with acid to produce the aglycones quercetin, kaempferol, and isorhamnetin. These aglycones are then quantified by HPLC using quercetin as the reference standard. The percentages of each flavonol glycoside are calculated based on the concentrations determined fro
