Embodiment 1

[0047] The quality control method for the simultaneous determination of the content of nine components by the full-time five-wavelength fusion method of licorice medicinal materials includes the following process steps:

[0048] (1) Preparation of the test solution: Take about 5 g of licorice powder, weigh it accurately, place it in a round bottom flask, add 100 mL of water accurately, weigh it, heat it under reflux for 2 hours, let it cool, and weigh it again. Make up for the lost weight with water, shake well, filter, accurately absorb 20 mL of the filtrate, add it to the AB-8 resin column, wash with 120 mL of distilled water, and then elute with 100 mL of 95% ethanol, collect the ethanol eluate, evaporate to dryness, Add 20% acetonitrile to the residue to dissolve it and transfer it to a 10mL volumetric flask, add 20% acetonitrile to the volume, shake well, filter, and take the filtrate to obtain the final product;

[0049] (2) Preparation of reference solution: Accurately ...

Abstract

The invention discloses a control method for simultaneously detecting content of nine components through a five wavelength merging method for licorice medicinal materials, which combines a modern analysis detecting method and a computer information merging method, accords with a principle of largest informatization, and effectively merges spectrum information and chromatograph information of index components so as to adopt a microscopic and comprehensive quantitative method to reflect the inner quantity of Chinese medicine materials. The quality control method is simple to operate, stable, reliable and good in reappearance, can be used in evaluation and control of the quality of the Chinese medicine materials and development and research of novel medicines, and especially can serve as one of the indexes for quality control and authenticity identification of the licorice medicinal materials.

Description

field of invention [0001] The invention belongs to the technical field of detecting the internal quality of Chinese medicinal materials by means of modern analysis and detection methods and computer information fusion methods, and relates to a quality control method for Chinese medicinal materials, in particular to a quality control method for simultaneous determination of the contents of nine components by a full-time five-wavelength fusion method for licorice medicinal materials . Background technique [0002] According to the Pharmacopoeia of the People's Republic of China in 2010, this product is the dried root and rhizome of Glycyrrhiza uralensis Fisch., Glycyrrhiza inflate Bat. or Glycyrrhiza glabra L., a leguminous plant. It was listed as "top grade" in "Shen Nong's Materia Medica". Licorice is sweet and flat in nature and has a long history of medicinal use. It is the most commonly used variety of Chinese herbal medicine. Licorice is a kind of simple qi medicine, w...
