Detection method for musk Xintongning preparation

Abstract

The invention relates to a detection method for a musk Xintongning preparation. The detection method comprises identification for artificial musk, identification for storax, ligusticum wallichii and borneol, identification for ginseng, identification for corydalis tuber, detection for tetrahydropalmatine, and analysis for characteristic fingerprints and mass spectrum of the musk Xintongning preparation. According to the invention, all the herbal medicines of the musk Xintongning preparation are identified, and the characteristic fingerprints of the musk Xintongning taking tetrahydropalmatine as the reference substance are determined. The detection method provided by the invention is good in stability, easy to operate, small in loss and high in accuracy; the shape of the chromatographic peak meets the detection requirements well, and is symmetrical; ligusticum wallichii, storax and borneol are identified by using the same thin layer plate, and are identified at the same time, so that the specificity is strong; the identification for ginseng can meet the conventional detection standard; meanwhile, the preparation time of a test sample is greatly shortened, and the detection efficiency is improved; the developing spots during identification for corydalis tuber are abundant, so that environment protection purpose is achieved; the mass spectrum identification adopted in the invention is special technology for the musk Xintongning preparation.

Description

technical field [0001] The invention relates to a detection method of Shexiang Xintongning preparation, which belongs to the field of traditional Chinese medicine detection. Background technique [0002] In the prior art, the identification and detection methods of Shexiang Xintongning preparation are: [0003] Identification: (1) Identification of artificial musk: extraction with ether, silica gel G thin-layer plate, development with toluene, and color development with dinitrophenylhydrazine test solution; [0004] (2) Styrax identification: ether extraction, silica gel G 254 TLC plate petroleum ether-n-hexane-ethyl formate-formic acid development, UV light inspection; [0005] (3) Identification of Rhizoma Chuanxiong: extract with ether, expand with n-hexane-ethyl acetate on a silica gel G thin-layer plate, and inspect under ultraviolet light; [0006] (4) Borneol identification: ethyl acetate extraction, PEG-20W is the gas chromatography identification of stationary ph...

AI Technical Summary

Problems solved by technology

[0014] (3) Identification of ginseng: the process is complicated, the process of washing with n-butanol sodium hydroxide and washing with water emulsifies seriously, and it cannot be separated well after being left overnight, and the operation time is very long;

[0015] (4) There is no identification of Yanhusuo

[0017] (1) Poor detection and poor resolution of other components except tetrahydropalmatine
