-
摘要: 目的 建立自乳化莪术油软胶囊中莪术油含量测定方法。方法 采用可见光分光光度法,将胶囊中内容物用无水乙醇稀释后,采用香草醛硫酸溶液显色,于(520±2)nm检测,测定其吸收度。结果 莪术醇浓度在40～320μg·ml-1范围内,线性关系良好(r=0.9979),回收率96.59%,RSD为1.03%。结论 本方法准确,可靠,适合用于自乳化莪术油软胶囊制剂的含量测定。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.
