Abstract

The invention belongs to the field of drug analysis and particularly relates to a method of establishing a fingerprint spectrum of an infant diarrhea stopping drug preparation. According to the method, by taking the infant diarrhea stopping drug preparation as a detection object, the method of establishing the fingerprint spectrum of the infant diarrhea stopping drug preparation is established, common characteristic peaks including peak 1, peak 2 liquiritin, peak 3 ammonium glycyrrhizinate, peak 4, peak 5, peak 6, peak 7 and peak 8 are affirmed, the peak 2 liquiritin is selected as an internal reference peak in the fingerprint spectrum, and a relative retention time of each common characteristic peak is determined; and in addition, with combination of information of a plurality of chromatographic peaks in the fingerprint spectrum, the quality of the infant diarrhea stopping drug preparation can be comprehensively and rapidly detected, so that comprehensive quality detection and whole quality control of the infant diarrhea stopping drug preparation are facilitated, and improvement on the use safety and stability of the drug is facilitated. Simultaneously, the method of establishing the fingerprint spectrum of the infant diarrhea stopping drug preparation has the advantages of high precision, good repeatability, high stability and the like.

Description

technical field [0001] The invention belongs to the field of drug analysis, in particular to a method for establishing the fingerprint of Erxieting drug preparation. Background technique [0002] Erxieting Granules is a traditional Chinese medicine compound preparation made from three medicinal materials: madder vine, black plum and licorice. It has the functions of clearing away heat and dampness, strengthening the intestines and stopping diarrhea. Since it was approved for marketing in 1999, Erxieting Granules have been well received by clinicians and consumers due to its definite curative effect, stable quality and safe use; the clinical re-evaluation of Erxieting Granules in 2011 showed that its efficacy in treating acute diarrhea in children It is good and safe, and can be used as the first choice for children's diarrhea medicine. [0003] At present, the quality control of Erxieting Granules is carried out through the standard No. WS3-160(Z-16)-2002(Z) recorded in the...
