目的建立祛瘀止痛胶囊中姜黄素的含量测定方法。方法采用KromasilC18柱(250mm×4.6mm);流动相:乙腈-4%冰醋酸溶液(48∶52);检测波长为430nm;柱温30℃。结果姜黄素进样量在0.0263～0.2104μg范围内呈良好的线性关系(r=0.9994),样品平均回收率为98.0%,RSD=1.58%(n=6)。结论此方法操作简便、快速、准确、可靠,可用于祛瘀止痛胶囊的质量控制。
Objective To establish a method for the determination of curcumin in Quyu Zhitong Capsules. Methods The Kromasil C18 column (250 mm × 4.6 mm) was used. The mobile phase was acetonitrile-4% acetic acid solution (48:52). The detection wavelength was 430 nm. The column temperature was 30 ℃. Results The curcumin injection showed a good linearity (r = 0.9994) in the range of 0.0263-0.2104 μg with an average recovery of 98.0% and a RSD of 1.58% (n = 6). Conclusion This method is simple, rapid, accurate and reliable and can be used for the quality control of Quyu Zhitong Capsules.
