Jie Chang Bao Kang Research Into Differentiation And Content

Jie Chang Bao Kang Research into differentiation and contentJie Chang Bao Kang Pellets is developed from some traditional Chinese medicines like Coptis chinensis and Astragalus membranaceus.It is effective to UC through clinical practice. The producer has carried out experimental researches systematically into its differentiation and contents.The thin-sheet method is most popular in the differentiation of traditional Chinese medicines and ready-made Chinese medicines. In the differentiation, product-contrast if and material-contrast if methods are often adopted, which are inexpensive and substantial and have the advantage of being widely used. The seven materials in the prescription are differentiated by the thin-sheet analysis.HPLC refers mainly to the testing method using a UV testing machine which has the advantages of high sensitivity, wide application and being easily measured in quantity. The content of Coptis chinensis is tested by HPLC and the average rate of reclamation is (RSD=98.7%) Astragalus membranaceus is mainly composed of Astragaloside. Astragaloside is absorbed at the ends of ultraviolet rays. The experiment needs strict operation and its result is greatly affected by noise. Ifowever, the experiment using the ELSD testing machine is not affected by outside conditions; the reagent is completely steamed away and the machine is easy to operate and sensitive. Therefore, the experiment testing the content of Astragalus membranaceus using ELSD proves the average rate of reclamation to be (RSD=98.6%). The two tasting methods are accurate and reliable and can be used to test the content of the reagent.
