Identification method of ginger in traditional Chinese medicine compound

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.

Problems solved by technology

[0003] Modern medical research has found that in the Chinese Pharmacopoeia of Chinese medicine compound varieties containing ginger (see Table 1), the quality standards of most varieties do not involve the identification method of ginger, while the other part of varieties (Fuzi Lizhong Pills, Sini Decoction, Xiaojian Although it involves the identification method of the drug, the separation effect of the method is not good for the preparation made in this study, and it cannot be detected

The applicant has used the identification methods of ginger or ginger-containing preparations in the Pharmacopoeia standard to conduct thin-layer chromatography identification of ginger in Fenghan cough granules. The results show that these methods cannot be detected and the separation effect is not good.
