Embodiment Construction

[0030] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0031] In this embodiment, representative Codonopsis pilosula is selected as the Chinese medicinal material, and Yinchaihu and Yeguanmen are selected as the easily mixed and counterfeit products for description.

[0032] Such as figure 1 As shown, the method for identifying Chinese medicinal materials and their easily mixed counterfeit products based on ion mobility spectrum and similarity includes the following steps:

[0033] Step 1: Select 8 batches of genuine Codonopsis pilosula samples, and pre-process the 8 batches of genuine Codonopsis pilosula samples and the samples of Yinchaihu and Yeguanmen:

[0034] Use a pulverizer (25000r / min, 3-10min) to process the above samples to obtain the corresponding powders. For each sample powder, accurately weigh 100mg of the sample powder and add it to 30mL of methanol solution. Stir magnetically at 100°C an...

Abstract

The invention discloses a method for identifying traditional Chinese medicinal materials and easily confused counterfeit medicines on the basis of ion mobility spectrometry and similarities. The ion mobility spectrometry is used as an analysis and test means, quantification processes include similarity computation and quality control charts, and the quantification method applicable to controlling the quality of the traditional Chinese medicinal materials can be provided. The method has the advantages that the method gives priority to quantitative evaluation rather than qualitative analysis dominant in traditional quality control identification of the traditional Chinese medicinal materials and is speedy, accurate and capable of achieving quantitative output, so that a novel evaluation thought is provided for the quality safety of the traditional Chinese medicinal materials in China, and the method is of important significance to quality control guarantee and clinical medication safety of the traditional Chinese medicinal materials.

Description

Technical field [0001] The invention belongs to the technical field of identification of Chinese medicinal materials, and particularly relates to a method for identifying Chinese medicinal materials and their easily mixed and counterfeit products. Background technique [0002] Chinese medicinal materials are an important basis for the efficacy of Chinese herbal compound prescriptions. The mixing of fake products greatly affects the efficacy of the drugs and threatens the health of patients. Take the common Chinese medicinal material Codonopsis for example. Radix Codonopsis is Codonopsis pilosula (Franch) Nannf, Codonopsis pilosula (Franch) Nannf.Var.modesta (Nannf) LTshen or Codonpsis tangshen. The dried roots of oliv have the effects of nourishing the middle and nourishing qi, invigorating the spleen and lungs, but due to the shortage of wild party parameters, artificially cultivated products often cannot meet the market demand, resulting in frequent occurrences of fake products...
