Abstract

The invention discloses a method for extracting a common traditional Chinese medicine from traditional Chinese medicinal materials and authenticating the common traditional Chinese medicine through MALDI-TOF-MS, and belongs to the technical field of biology. According to the method, the traditional Chinese medicinal materials are smashed at high speed, total protein and polypeptide are extracted from the traditional Chinese medicinal materials, dialysis desalination is conducted, then the MALDI-TOF-MS is adopted for detection, and a traditional Chinese medicinal material protein map is obtained. The simple protein extracting technology and Malditof are combined for authenticating the protein maps of the common traditional Chinese medicinal materials such as astragalus membranaceus, ginseng and liquorice. The method has the advantages of being easy and reliable to implement, and provides selections and references for authenticating the common traditional Chinese medicinal materials.

Description

technical field [0001] The invention relates to a method for extracting common Chinese medicines from Chinese medicinal materials and identifying them by MALDI-TOF-MS, in particular to a method for identifying commonly used Chinese medicinal materials astragalus, ginseng and licorice by using Malditof, and belongs to the field of biotechnology. Background technique [0002] Chinese herbal medicines are the raw materials of Chinese herbal decoction pieces, Chinese herbal extracts and Chinese patent medicines. Its front end is medicinal plants, medicinal animals, medicinal minerals and their specific medicinal parts, or the base of Chinese herbal medicines. Accurate identification of Chinese medicinal materials is a basic link in the operation and development of Chinese medicine, and has always attracted attention. The relevant national medicinal material standards mainly confirm the source species based on taxonomic research, limit the medicinal parts, and basically clarify t...
