Preliminary Study on Chemical Components of Derris eriocarpa How.

Objective:To study the chemical constituents of Derris eriocarpa How.by preliminary test.Methods:The mixtures were extracted from Derris eriocarpa How.with purified water,95% ethanol by chemical reaction identification method.Results:Through preliminary test,the chemical components of amino acids,polypeptide,protein,saccharide,polysaccharide,glycoside,saponin,organic acid,flavone,anthraquinone,cardiac glycoside,phytosterin,triterpene and phenols were positive reactions and others were negative reactions.Conclusion:The preliminary test indicate that Derris eriocarpa How.may contain effective components such as amino acids,polypeptide,protein,saccharide,polysaccharide,glycoside,saponin,organic acid,flavone,anthraquinone,cardiac glycoside,phytosterin,triterpene and phenols.The research provides foundation for further study of the chemical compositions and biological activities of Derris eriocarpa How.
