Abstract Objective: To develop a high performance liquid chromatography (HPLC) method for determining three monomers of ginkgolic acids, GA 13∶0, GA 15∶1 and GA 17∶1, in mouse plasma. Methods: Plasma samples were treated with acetonitrile for protein precipitation. The analytical column was SinoChrom ODSAP C18(250 mm×4.6 mm, 5 μm).The mobile phase consisted of a mixture of methanol3% acetic acid (92∶8) at a flow rate of 1.0 mL· min-1. The detection wavelength was at 310 nm. Results: Standard curves of GA 13∶0, GA 15∶1 and GA 17∶1 were linear in the range of 0.135-20 μg·mL-1, 0.129-20 μg·mL-1, and 0.211-22 μg·mL-1, respectively (both r＞0.9990). The lower limit of quantification were 0.135, 0.129 and 0.211 μg·mL-1, respectively. The extraction recoveries＞70.2% (n=5) and the accuracies were 95.2%-101.5%. The intra-day and inter-day precisions were lower than 6.2% and 9.5 % (n=5), respectively. Conclusion: The HPLC method was successfully built for determining GA 13∶0, GA 15∶1 and GA 17∶1, which was simple and sensitive, accurate with reproducible, and suitable for clinical pharmacokinetic study. ［Key words］ginkgolic acid monomer; high performance liquid chromatography; mouse
