Abstract

The invention relates to the technical field of traditional Chinese medicine detection, in particular to a specific chromatogram construction method and a quality detection method of schizonepeta. Liquid chromatography conditions, mobile phase compositions and an elution procedure are controlled, and a specific chromatogram of nonvolatile constituents of the schizonepeta is established; suitable gas chromatography conditions are selected, and a specific chromatogram of volatile constituents of the schizonepeta is established; specific peaks of the specific chromatograms are marked; the liquidchromatography elution procedure is adjusted, and the content of hesperidin in the schizonepeta is determined; and at the same time, a quality control method of the schizonepeta is established, the quality control method comprises the steps that the schizonepeta specific chromatograms are used for evaluating the schizonepeta, the content of the hesperidin is determined, the quality control methodfurther comprises the steps that thin layer chromatography identification is conducted, heavy metal and hazardous elements are examined, the pesticide residue amount is determined, extraction determination is conducted, and the quality of the schizonepeta is evaluated from the perspective of effectiveness and safety. The quality detection method has the advantages of being simple, fast, stable, reliable, high in precision, good in reproducibility, easy to master, and the like.

Description

technical field

[0001] The invention relates to the technical field of traditional Chinese medicine detection, in particular to a construction method and a quality detection method of a nepeta nepeta characteristic map. Background technique

[0002] Schizonepeta, mild in nature, pungent in taste, has the effects of relieving exterior wind, clearing rash and eliminating sores, and is used for colds, headaches, measles, rubella and sores, and is one of the commonly used traditional Chinese medicines. In today's increasingly concerned about the quality of medicines, the quality control of Chinese herbal medicines is very important. With the development of chromatographic technology, the quality standard of Nepeta chinensis includes not only simple properties, identification, routine inspection and determination of extracts, but also the determination of HPLC fingerprint. Traditional Chinese medicine fingerprint is a comprehensive and quantifiable means of identification, and i...
