目的:探讨方法使用高效液相法测定其中隐丹参酮含量的方法。方法:用HPLC法对丹参酮片中隐丹参酮进行含量测定,并进行相关精密度、重复性、稳定性考察。结果:取丹参酮片3批样品,按上述方法分别测定,按外标法以峰面积计算样品中隐丹参酮的含量,结果分别为每片含隐丹参酮31.45,31.76,31.81 mg。结论:该方法用于考察丹参酮片中隐丹参酮含量有分离效果好、灵敏、准确等优点,可用于该产品的质量控制。
Objective: To explore a method for determination of cryptotanshinone content by HPLC method. Methods: The content of cryptotanshinone in tanshinone tablets was determined by HPLC, and the related precision, repeatability and stability were investigated. Results: Three batches of samples of tanshinone tablets were taken and determined according to the above methods. The content of cryptotanshinone in the sample was calculated by the external standard method. The results showed that each tablet contained cryptotanshinone 31.45,31.76,31.81 mg. Conclusion: The method for the determination of tanshinone tablets cryptotanshinone content separation effect is good, sensitive and accurate, etc., can be used for the quality control of the product.
