| Abstract: | Objective To establish the best extraction method for the alkaloids in Aconitum flavum seeds,and provide scientific basis for the effective use of Aconitum flavum seed alkaloid.Methods By the chromogenic reaction of the alkaloid and TLC for the qualitative identification of Aconitum flavum seed alkaloids;the orthogonal experimental design and UV spectrophotometry were used for quantitative analysis.Results The optimal extraction method was as follows：extraction 30rain,concentration of ethanol 60%,ratio for solid-liquid 1：20. The content of total alkaloids was 0.19%.Conclusion The method is simple with high extraction rate of ultrasonic extraction and has utility value,which can provide scientific basis for further studies on chemical constituents of Aconitum flavum seeds. |
