Abstract

The invention discloses a headache treating capsule fingerprint spectrum detection method. The method comprises the following steps of: (1) preparing a test solution of the headache treating capsule;(2) establishing a fingerprint by an HPLC (high performance liquid chromatography) chromatographic technique; and (3) on the basis of the fingerprint, the content of 5 main characteristic chemical components is measured. Experiments prove that the fingerprint detection technology provided by the invention can comprehensively reflect the internal quality of the headache treating capsule product qualitatively and quantitatively, and provides a key technology reference for improving the quality standard of the medicine.

Description

Technical field [0001] The invention relates to a method for detecting fingerprints of Toutongning capsules, and belongs to the technical field of detection and analysis of Chinese patent medicines. Background technique [0002] The fingerprint of traditional Chinese medicine is a comprehensive and quantifiable identification method. It is based on the qualitative basis of traditional Chinese medicine, using modern analysis and detection technology, which can systematically, integrally and exclusively characterize the common and inherent characteristics of traditional Chinese medicine. feature. Nowadays, the quality standards of traditional Chinese medicine formulated by "Chinese Pharmacopoeia" must not only conform to the characteristics of traditional Chinese medicine, but also the method of controlling the quality of Chinese herbal medicine by the fingerprint of traditional Chinese medicine has been recognized internationally. Both traditional Chinese medicine and traditional...
