Isoginkgetin is a biflavonoid compound isolated from the leaf extracts of Ginkgo biloba . In this study, an liquid chromatography–tandem mass spectrometry (LC/MS/MS) with liquid–liquid extraction was developed and validated for the analysis of isoginkgetin in rat plasma. In the process of chromatographic separation, selected reaction monitoring transitions for isoginkgetin and IS were m/z 566.8 → 134.7 and m/z 430.8 → 269.3, respectively. The validation parameters including selectivity, linearity, LLOQ, accuracy, precision, matrix effect, stability and recovery were satisfactory. The intra‐ and inter‐batch precision (RSD) were <12.1% in plasma, while the accuracy (RE) was within ±14.3%. This method was employed in a pharmacokinetic study on rats after the intravenous administration of isoginkgetin.
