Abstract

The invention relates to a method for detecting the quality of moghania macrophylla. The method comprises identification and content measurement. Compared with the prior art, the method for detecting the quality of the common traditional Chinese medicament, moghania macrophylla, is high in stability and sensitivity, and can authenticate the original medicinal materials more simply and intuitively, so as to provide a basis for the qualitative and quantitative detection of the moghania macrophylla. Moreover, the quality and the curative effect of the moghania macrophylla can be guaranteed better, and the medicinal resources of the moghania macrophylla can be utilized better.

Description

technical field [0001] The invention relates to a quality detection method of traditional Chinese medicine, in particular to a quality detection method of Daye Qianjinba. Background technique [0002] Flemingia macrophylla (Willd.) Prain. is the dried root of Flemingia macrophylla (Willd.) Prain. in Papilionaceae. The quality standard of the original plant of Qianjinba, Daye Qianjinba, is only the description of the properties of the medicinal material and the records of its microscopic characteristics, which has a great influence on the development of new drugs. [0003] Plants of the genus Echinacea mainly contain flavonoids, terpenes, steroids and other components, among which flavonoids are the main substances, most of which are isoflavones, and isoflavones substituted by isopentenyl account for the majority. [0004] In recent years, with the deepening of research, more and more medicinal materials are used in various clinical preparations. It has strong pharmacologica...
