Objective: To establish a method for determination of aconite alkaloids in Fengshi Gutong tablets. Methods: Analysis was performed on a WatersXSelect® CSH C18(250 nm×4.6 mm, 5 μm) column with mobile phase consisting of 0.1% acetic acid aqueous solution, acetonitrile and methanol with gradient elution at a flow rate of 1.0 mL·min-1. The detection wavelength was set at 245nm and the column temperature was 30 ℃. Results: Twelve aconite alkaloids could be separated well. When the injection amounts of ranaconitine, benzoylmesaconine, benzoylmesaconine, benzoylmesaconine, acoforestinine and beiwutine, mesaconitine, hypaconitine, indaconitine, aconitine, yunaconitine, bulleyaconitine A were 0.022 8-0.136 6 μg, 0.041 5-0.249 0 μg, 0.033 5-0.200 8 μg, 0.033 9-0.203 1 μg, 0.033 1-0.198 6 μg, 0.040 3-0.241 6 μg, 0.030 2-0.181 4 μg, 0.028 6-0.171 6 μg, 0.033 6-0.201 6 μg, 0.030 3-0.181 9 μg, 0.063 4-0.381 5 μg and 0.034 0-0.204 2 μg, respectively, the peak area showed a good linear relationship with the injection amounts. The average recovery rates of 12 aconite alkaloid components ranged from 93.6% to 101.5%, and the RSD ranged from 0.55% to 2.6%. The average contents of ranaconitine, benzoylmesaconine, benzoylmesaconine, benzoylmesaconine, acoforestinine and beiwutine, mesaconitine, hypaconitine, indaconitine and yunaconitine in three batches of Fengshi Gutong tablets (batch No. 211227, 220823 and 230425) were 0.492 μg, 65.78 μg, 7.319 μg, 10.164 μg, 1.068 μg, 5.583 μg, 2.573 μg, 5.865 μg, 2.021 μg, 2.050 μg, respectively. And aconitine and bulleyaconitine A were not detected. Conclusions: The established method is accurate and reliable, and can be used for the determination of 12 aconite alkaloids compounds in Fengshi Gutong tablets to achieve comprehensive quality control of preparations.
