Abstract:Objective To determine the content of diester diterpenoid alkaloids in Radix Aconiti flavi et penduli. Methods HPLC method was applied to determine the contents of diester diterpenoid alkaloids in the roots of Aconiti flavi et penduli. Results The study on the quality control showed that the new method by HPLC was good in sensitivity and specificity. The linear range of Aconitine, Hypaconitine, and Mesaconitine was 0.06-0.65 μg (r=0. 9996), 0.19-1.96 μg (r=0. 9994), and 0.22-2.25 μg (r=0. 9992) respectively. The average recovery (RSD) value of Aconitine, Hypaconitine, and Mesaconitine was 96.9% (1.5%), 97.1% (1.8%), and 96.3% (1.9%) respectively. Conclusion The method of identification and quantification is simple, reliable, and reproducible, and it can be used effectively for quality control of the roots of Aconiti flavi et penduli.
Keywords:Aconiti flavi et penduli  diester diterpenoid alkaloids  HPLC
