Abstract:

An analytical method was developed for the determination of ginkgolic acids in ginkgo biloba extract and its preparations by ultra high performance liquid chromatography-triple quadrupole mass spectrometry. A chromatographic column, Agilent Poroshell 120 EC-C18(50 mm×3.0 mm, 2.7 μ m), was used with methanol-1% acetic acid (90 : 10, v/v) as the mobile phase. The ginkgo acids were detected by electrospray ionization mass spectrometry in negative mode with multiple reaction monitoring (MRM) mode. Ginkgo acids C13 : 0, C15 : 1 and C17 : 1 possessed good linear correlations in the mass concentration range from 2 to 200 μ g/L, with the correlation coefficients more than 0.999. The mean recoveries at the spiked levels of 5, 20 and 100 μ g/L were in the range of 86.3%-114.3%, and the RSDs were 0.5%-13.6%. The limits of detection and quantification were 0.003-0.08 μ g/g and 0.01-0.19 μ g/g, respectively. The method was successfully applied to the analysis of actual samples.
