Abstract

The invention discloses a quality control method of liquorice formula granules, belonging to the technical field of analysis of traditional Chinese medicines. The method is used for identifying the liquorice formula granules by adopting a high performance liquid characteristic chromatography, and comprises the following steps: (a) preparing a reference substance solution; (b) preparing a test solution; (c) detecting by adopting the high performance liquid chromatography to obtain the characteristic chromatogram of the liquorice formula granules. According to the established high performance liquid characteristic chromatogram of the liquorice formula granules, five characteristic peaks can be obtained, and as shown in the figure, the peak marked by No. 5 is a reference peak, and the retention time is taken as the following measured values: 8.066 minutes (peak 1), 8.943 minutes (peak 2), 17.708 minutes (peak 3), 21.245 minutes (peak 4) and 30.618 minutes (peak 5) (S). Every gram of liquorice formula granules is equivalent to 10-20g of crude drug. The method has the characteristics of being high in specificity and accuracy; the detection method is scientific and advanced and has operability. The characteristic chromatogram technology is applied to the quality control of the traditional Chinese medicine formula granules, so that the product quality is effectively controlled.

Description

technical field [0001] The invention relates to a quality control method of traditional Chinese medicine formula granules, in particular to a method for establishing a high performance liquid chromatography characteristic map of licorice formula granules, and a characteristic map of licorice formula granules obtained by the method, belonging to the field of traditional Chinese medicine analysis. Background technique [0002] Traditional Chinese medicine formula granules are prepared by extracting, concentrating, drying, and granulating the Chinese herbal decoction pieces as raw materials. As a new form of decoction pieces, they can replace Chinese herbal decoction pieces for clinical syndrome differentiation and treatment, and can be added or subtracted according to the symptoms. It ensures the efficacy of traditional Chinese medicine decoction pieces. Compared with the traditional Chinese medicine decoction, it is convenient to take, the dosage is small, the quality is contr...
