Abstract
Aim: We aimed to develop a rapid and accurate LC-MS/MS method for determining the concentration of aloesone in rat plasma, and to investigate its pharmacokinetics. Methods: The rat plasma samples were extracted using acetonitrile. Chromatographic separation was achieved using a Kinetex XB-C18 column, with a mobile phase of methanol and water (containing 0.1‰ formic acid) in a gradient elution. An ESI source, operating in positive ion mode with multiple reaction monitoring, was utilized. Results & conclusion: The developed method meets all the requirements for methodological validation, and it was successfully applied in the pharmacokinetic study. It was observed that oral administration of aloesone in rats resulted in rapid absorption (time to reach Cmax: 0.083h) but low bioavailability (12.59%).
