ABSTRACT
(+)-Borneol, a bicyclic monoterpene, has been shown to possess valuable biological properties and potential as a pharmaceutical agent due to anti-inflammatory, anti-oxidant and GABA receptor-enhancing functions; it also enhances the permeability of the blood brain barrier to improve the efficacy of CNS drugs. In this study, we have developed a simple, selective, and rapid liquid chromatography-tandem mass spectrometry method for the assay of (+)-borneol in rat plasma. Verapamil was used as an internal standard. Plasma samples were deproteinized using methanol. The analyte was detected by a mass spectrometer with positive atmospheric pressure chemical ionization by multiple reaction monitoring mode for transitions at m/z [Mâ¯+â¯H]+ 137.2â¯ââ¯81.0 for (+)-borneol and 455.2â¯ââ¯165.1 for verapamil. The method has been fully validated to ensure good selectivity, a satisfactory lower limit of quantification at 10.0â¯ng/mL, acceptable intra- and inter-day accuracy, and high precision. The method was used for the pharmacokinetic evaluation of (+)-borneol in Sprague-Dawley rats after intravenous, oral, and sublingual administration. The results indicate that oral bioavailability of (+)-borneol was extremely low but sublingual administration yielded rapid absorption and favorable bioavailability of (+)-borneol.
