Locating chromatographic peaks of the component to be detected, verifying relative retention values of other 4 components under different chromatographs and chromatographic columns through the algorithm in the step eleven, and determining that the results are as shown in the following table 6 and have no obvious influence;

comparing the QAMS (one-test-multiple-evaluation method) and ESM (external standard method) measuring results, respectively measuring 5 components of the ten-flavor deer capsule by adopting QAMS and ESM according to the chromatographic conditions described in the step four. The results are shown in the following table 7,

TABLE 7 comparison of the results obtained by the one-test-multiple-evaluation method with the external standard method (n ═ 6)

The ten-flavor deer capsule, the preparation method thereof and the ginsenoside content analysis method establish a one-test-multiple-evaluation method with simple operation and reliable result by measuring the content of various ginsenosides in the ten-flavor deer capsule, and solve the problems of deficiency and high price of a ginsenoside reference substance and the like. Testing toGinsenoside Rb1As internal standard, by ginsenoside Rg1Ginsenoside Re, ginsenoside Rf and ginsenoside Rb3The content thereof is calculated with respect to the correction factor. As a result, the result obtained by the method has no significant difference compared with the external standard method. The analysis method supplements the quality evaluation method of the multi-drug effective components of the ten-flavor Xianglu capsules, and more effectively controls the product quality.
