Abstract

The invention discloses a quantitative fingerprint spectrum analysis method for components in ginger and ginger pinellia percolate. The method comprises the following steps: (1) preparing a test solution and a reference substance mixed solution; and (2) analyzing the reference substance mixed solution and the test solution by adopting a high performance liquid chromatograph to obtain the quantitative fingerprint spectrum of the components in the ginger and pinellia percolate. Wherein the chromatographic conditions are as follows: a high performance liquid chromatography system is selected as an instrument, and a Waters Atlants T3 chromatographic column (100mm * 2.1 mm, 3.0 [mu] m) is selected as a chromatographic column; a DAD detector is adopted; the flow rate is 0.30 mL / min, the column temperature is 25 DEG C, and the sample injection volume is 3-5 [mu] L; taking pure water and acetonitrile as mobile phases; and (3) selecting chromatographic peaks existing in chromatograms of different batches of ginger and ginger pinellia percolates as common peaks, calculating component contents of different batches of percolates, and calculating similarity, thereby providing scientific basis and technical support for quality control of the ginger and ginger pinellia percolates. The method provided by the invention makes up for the deficiency of a method for detecting chemical components of a common goldenrop capsule production intermediate.

Description

technical field [0001] The invention relates to a detection method of traditional Chinese medicine, in particular to a quantitative fingerprint analysis method of components in ginger and pinellia percolation liquid. Background technique [0002] Xiaochaihu capsule is a compound preparation made from Bupleurum baicalensis, Scutellaria baicalensis, licorice, Codonopsis pilosula, jujube, ginger and Pinellia ginger through decoction, percolation, concentration and other processes. See alternation of cold and heat, chest fullness, loss of appetite, upset and vomiting, bitter mouth and dry throat, etc. The intermediates of Xiaochaihu Capsules include the infiltration liquid of two kinds of medicinal materials such as ginger and pinellia, the mixed decoction liquid of five medicinal materials such as Bupleurum, scutellaria baicalensis, licorice, Codonopsis pilosula, and jujube, as well as various concentrated solutions. [0003] The internationally recognized concept of "quality ...
