- W2382505903 abstract "Objective To develop a qualitative method for the quick determination of proanthocyanidins in Ginkgo Folium preparation(GFP),and to provide the objective evidence for the quality control of proanthocyanidins.Methods NP-HPLC and HPLC-DAD-MS methods were developed to analyze the composition of proanthocyanidins in Ginkgo Folium proanthocyanidin extract,grape-seed extract,GFP,and adulterate GFP.Results The proanthocyanidins were separated in normal phase mode according to their degree of polymerization.The proanthocyanidins from grape-seed extract,which consisted of(epi)catechin,had only one characteristic absorption band in HPLC chromatograms for each degree of polymerization;And proanthocyanidins of GFP,which consisted of(epi)gallocatechin and(epi)catechin,had two or three characteristic absorption bands for each degree of polymerization.Conclusion The HPLC method is applicable for the qualitative analysis of proanthocyanidins and the identification of authentic and adulterated proanthocyanidins in GFP." @default.
