Abstract

The invention discloses an identification method of ginger in a traditional Chinese medicine compound and in particular relates to a thin-layer identification method of ginger in a traditional Chinese medicine compound. The identification method comprises the following steps: preparing a reference crude herb solution; preparing a solution of test articles; preparing a negative sample solution; carrying out sample application on a same silica gel G thin-layer plate by using a capillary sample applicator; putting the thin-layer plate in a chromatography cylinder, developing the thin-layer plate with a developer and taking out and airing the thin-layer plate; viewing the thin-layer chromatoplate and identifying the obtained results, wherein the test article chromatogram is in a position corresponding to the reference crude herb chromatogram and shows principal spots in the same color while a negative sample does not have the spots. The identification method is simple in process, has good separating effects and extremely strong specificity, has the effect of further improving the accuracy of identification of the component ginger in the traditional Chinese medicine compound and has huge popularization and application potentials in the field of identification of medicines related to ginger.

Description

technical field [0001] The invention relates to a method for identifying ginger in a compound Chinese medicine, in particular to a thin-layer identification method for ginger in a compound Chinese medicine. Background technique [0002] It is the fresh or dry rhizome of Zingiber officinale Rose. Excavated in autumn and winter to remove fibrous roots and silt, do not dry in the sun or dry in the sun or dry at low temperature. Those that are not dried in the sun are called "ginger", and those that are freshly sliced ​​and dried in the sun or at low temperature are called "dry ginger slices", which are mainly produced in Shandong, my country. Ginger is a traditional antiemetic medicine, which has the functions of relieving the exterior and dispelling cold, warming the middle to relieve vomiting, resolving phlegm and relieving cough, and detoxifying fish and crabs. Indications for anemofrigid cold, stomach cold vomiting, cold phlegm cough, fish and crab poisoning. Ginger can ...
