Abstract

The invention relates to a method for identifying ginger in Jiangzhuru traditional Chinese medicine formula granules. The identification method comprises the following steps: providing a reference substance solution, preparing a test solution, and detecting the reference substance solution and the test solution by adopting a thin layer chromatography, wherein a reference substance in the reference substance solution contains zingiberone and 6-gingerol; the step of preparing the test solution comprises the following steps: preparing an extracting solution containing zingiberone and 6-gingerol from the ginger and bamboo shavings traditional Chinese medicine formula granules; then adopting a polyamide column to perform column chromatography on the extracting solution containing zingerone and 6-gingerol, wherein the conditions of column chromatography are as follows: the polyamide column is adopted as a chromatographic column, an eluent is a methanol solution with the methanol volume percent of 25%-55%, and isocratic elution is adopted as an elution mode. According to the method, the ginger in the Jiangzhuru traditional Chinese medicine formula granules is identified based on the thin-layer chromatography, and a scientific, rapid and low-cost new method is provided for quality control of Jiangzhuru traditional Chinese medicine formula granule products.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine detection, in particular to a method for identifying ginger in Jiangzhuru traditional Chinese medicine formula granules. Background technique [0002] Jiangzhuru traditional Chinese medicine formula granules are obtained by extracting Jiangzhuru decoction pieces with water, concentrating and drying them. Ginger bamboo rut decoction pieces are processed from bamboo rut, which is roasted or fried with ginger juice until yellow. It is shaped like a bamboo rut, with a yellow surface and a slight ginger aroma. Jiang Zhuru is good at resolving phlegm and relieving vomiting. [0003] Jiangzhuru traditional Chinese medicine formula granules, the problems faced in its identification include: traditional Chinese medicine formula granules are granules made of single traditional Chinese medicine decoction pieces by water extraction, separation, concentration, drying and granulation. Tra...
