| Abstract: | Objective:Establishing a simple useful method of the ultraviolet spectrophotometric to determine the arteannuin element content,providing the fast basis for screening and shopping high quality arteannuin.Method:Carrying on the wave length scanning with the ultraviolet spectrophotometer to arteannuin element standard solution, establishing the standard curve, according to standard curve determination sample content. Results:Arteannuin element most suitable absorption wave length is 290 nm, and the extinction-density regression equation is:Y=0.043X+0.006. The different arteannuin element sample content has the difference.Conclusion:The method of ultraviolet spectrophotometric determining arteannuin element content operation is quickly,simple and accurate. |
