Central control detection method of 7-ACA derivative

The invention relates to a central control detection method of 7-ACA derivatives. The method comprises the following steps: S1, preparing a test solution and a contrast solution; s2, taking a test solution with the volume of V for test and a contrast solution with the volume of V contrast into a high performance liquid chromatograph for testing, and respectively obtaining chromatograms of the test solution and the contrast solution; s3, respectively obtaining an absorption peak area A contrast in the contrast solution and an absorption peak area A test in the test solution; and S4, calculating the content of the 7-ACA derivative in the test sample. 一种7-ACA衍生物的中控检测方法,包括以下步骤：S1.配制供试液和对照液；S2.取体积为V供试的供试液和体积为V对照的对照液至高效液相色谱仪中进行测试，并分别获得供试液和对照液的色谱图；S3.分别获得对照液中的吸收峰面积A对照以及供试液中的吸收峰面积A供试；S4.计算7-ACA衍生物在供试品中的含量。
