| Abstract: | OBJECTIVE:To establish a UV-Vis spectrophotometric method for content determination of Curdione in Nano-micelles loaded with Curdione.METHODS:Curdione was colored by sulfuric acid-vanillin reagent.The absorbance was measured by visible-spectrophotometry at a wavelength of 500nm.RESULTS:The content of Curdione in the range of 0.050～ 0.400mg· mL-1 was in accordance with the Lambert-Beer law(r=0.999 3).The average recovery was 99.14%,and the RSD was 1.23%(n=9).CONCLUSION:This method is simple,accurate and suitable for the content determination of curdione in Nano-micelles loaded with Curdione. |
