ABSTRACT
Cirsimarin is a bioactive antilipogenic flavonoid isolated from the cotyledons of Abrus precatorius and represents one of the most abundant flavonoids present in this plant species. Cirsimarin exhibits excellent antioxidant, lipolysis, and other biological properties; it can effectively trigger lipid movement and demonstrates antiobesity effects. In this work, an ultra-high-performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS) method was developed for the determination of cirsimarin in rat plasma after intravenous administration. A standard curve of cirsimarin in blank rat plasma was generated over the concentration range of 1-3000 ng/mL. Six rats were administered cirsimarin intravenously (1 mg/kg). The method only required 50 µL of plasma for sample preparation, and the plasma proteins were precipitated with acetonitrile to pretreat the plasma sample. The precisions of cirsimarin in rat plasma were less than 14%, while the accuracies varied between 92.5% and 107.3%. In addition, the matrix effect varied between 103.6% and 107.4%, while the recoveries were greater than 84.2%. This UPLC-MS/MS method was then applied in measuring the pharmacokinetics of cirsimarin in rats. The AUC(0-t) values of cirsimarin from the pharmacokinetic analysis were 1068.2 ± 359.2 ng/mL·h for intravenous administration. The half-life (t 1/2) was 1.1 ± 0.4 h (intravenous), indicating that the metabolism of the compound was quick in the rats. Exploring the pharmacokinetics of cirsimarin in vivo can help better understand its metabolism.
