Abstract

The invention relates to a detection method of ginseng formula granules, and belongs to the field of modernization of Chinese traditional medicine. Octadecylsilane chemically bonded silica is used as a filler; the column is CAPCELL PAK MG, 4.6*250 mm, and 5 microns; acetonitrile is used as a mobile phase A, water is used as a mobile phase B, and gradient eluting is carried out; the detection wavelength is 203 nm, the number of theoretical plates is not lower than 6000 in terms of ginsenoside Re peaks and is not lower than 200000 in terms of ginsenoside Rd peaks; in the preparation of a reference substance solution and a test solution, 5 microliters of the reference substance solution and 5 microliters of the test solution are adsorbed precisely respectively and then are injected into a liquid chromatograph, collection lasts for 120 minutes, and a chromatogram map is recorded. According to the detection method, the ginseng formula granules are qualitatively detected relatively comprehensively, and the method is a qualitative ginseng formula granule detection method with relatively high specificity.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicine modernization, and in particular relates to a method for detecting characteristic spectrum of ginseng formula particles. Background technique [0002] Ginseng is the dried root and rhizome of Araliaceae Panax ginseng C.A.Mey. It is mostly excavated in autumn, washed and sun-dried or dried. The cultivated ginseng is commonly called "garden ginseng"; the one that grows naturally in the wild state of the forest is called "forest ginseng", and is commonly called "seed sea". It mainly contains ginsenosides, the content of total saponins in various ginseng is usually 2% to 12%, and the content of total saponins in branch roots and fibrous roots is higher than that in tap roots; among them, it is mainly damane-type tetracyclic triterpene saponins, such as ginsenosides R a1 , R a2 , R a3 , R b1 , R b2 , R b3 , R c , R d , R e , R f Wait. Hydrolysis can get ginsengdiol or panaxatrio...
