Abstract:
Objective To establish the characteristic spectrum of ginkgo leaf tablets,ginkgo leaf capsules,and ginkgo leaf dropping pills.Methods HPLC-ELSD analysis was performed on an Agilent Poroshell 120 EC-C18 column(150 mm×4.6 mm,2.7 μm)with the methanol-0.1% formic acid as mobile phase at the gradient elution mode,flow rate was 0.8 mL·min-1.Results Referring to the reference extract,a total of 12 peaks were established in the characteristic spectrum and selected as the characteristic common peaks.Conclusion The established method was simple and sensitive with good reproducibility,so it could be used to control the quality of ginkgo leaf preparations.
