Abstract:
The study was aimed to investigate the effects of single and multiple oral administration of mungbean (Phaseolus radiatus L.) seed extract (ME) on the pharmacokinetics of aconitine in rats. The Sprague-Dawley rats were randomly divided into three groups (six rats each group). In group 1, rats were orally administered 500 µg/kg aconitine after receiving a single oral dose of 1 g/kg ME. In group 2, rats were orally administered with 500 µg/kg aconitine at day 7 of treatment with 1 g/kg/day ME. In group 3, rats were orally administered with 500 µg/kg aconitine. Blood samples were collected at different time points (0.083, 0.25, 0.5, 1.0, 1.5, 2.0, 4.0, 6.0, 8.0 and 10.0 h). The concentration of aconitine in rats plasma was determined by a fully validated ultra-high-performance liquid chromatography coupled with mass spectrometry method. The results showed that single and multiple oral co-administration of ME significantly altered the pharmacokinetic parameters of aconitine.
