| Abstract:OBJECTIVE To study the determination method of self-emulsifying Curcuma oil soft capsule. METHODS The content of soft capsules was diluted by anhydrous alcohol, and then colored by sulfuric acid-vanillin reagent. RESULTS The absorbance was measured at (520±2) nm. Curcumenol revealed linearity over the arrange of 40-320μg·ml-1, the average recovery was 96.59%,and RSD was 1.03%. CONCLUSION This method is accurate, reliable, and it is suitable for the content of determination of self-emulsifying curcuma oil soft capsules. |
