| description | The invention provides a method for determining the content of rosmarinic acid in Xinhuang tablets. The method is carried out by adopting a high performance liquid chromatography, and the chromatographic conditions are as follows: a chromatographic column is Welch AQ-C18, 4.6 * 250 mm and 5 [mu] m, a mobile phase is acetonitrile and a 0.1% phosphoric acid aqueous solution in a ratio of 19: 81, the flow velocity is 0.8 mL/min, the detection wavelength is 342 nm, and the column temperature is 30 DEG C. The determination method is reliable, simple, convenient, high in specificity and good in repeatability, stability and precision, can be used as a method for determining the content of the Xinhuang tablets, provides technical support for determination of the content of rosmarinic acid in the Xinhuang tablets, and is used for improving the product quality of the Xinhuang tablets.
