  • A liquid chromatographic-electrospray mass spectrometric method was developed for the determination of ginkgolides and bilobalide and was applied to the analysis of commercial products of Ginkgo biloba leaf extracts. Adducts of these compounds with ammonium, proton and sodium were detected and their relative abundance depended on the electrospray fragmentor voltage. The relative standard deviation (RSD) was improved from > 17% to < 6%, when three adduct ions of (M + H)+, (M + NH4)+ and (M + Na… CONTINUE READING
