I believe that with the further development of science and technology , there will be more and more relevant research , as early as possible to achieve its maximum medicinal value. Method: After a preliminary literature review to determine this experimental program , This experiment crushed the Plumula（）.And combined the extract,concentrated it until we could’t smell the taste of alcohol, the concentrate was adjusted to pH=3 with 1% hydrochloric acid, then filtered with gauze. The filtrate was adjusted to pH=9 with ammonia, the solvent extraction with dichloromethane,concentrated the extracts, we got 200g dark yellow precipitate., which was the total alkaloids of plumula. After a HPLC analysis to the total alkaloids, explored the analytical conditions of HPLC, made sure the best of the analytical conditions of HPLC.The characteristic spectrum was bulit in the best of the analytical conditions of HPLC. Results: It was found that the kind of alkaloids in Plumula contained far more than reported in the literature through the result of characteristic spectrum. It indicated that the Plumula contains a large number of unknown structure of alkaloids. Conclusion:The experimental data obtained in this experiment may provided a theoretical basis for the exploration and technology odevelopment of Plumula total alkaloids, and lay the foundation for future study of the pharmacological effects .
