Embodiment 1

[0023] Example 1: Near-infrared rapid determination of red ginseng raw materials

[0024] As an API, red ginseng is an important component of various Chinese patent medicines and other related products. Only by ensuring the quality of the API can the safety and reliability of the final product be ensured. Therefore, the detection of the API is very important. The testing of traditional raw materials in pharmaceutical companies usually takes some samples for routine chemical analysis, which has the problem of insufficient representativeness of sampling inspection, and it is difficult to guarantee the quality of all batches. At the same time, conventional analysis methods are usually cumbersome and time-consuming. Near-infrared spectroscopy can solve these problems well and realize rapid detection of all batches of samples.

Embodiment 2

[0056] Example 2: Near-infrared rapid determination of red ginseng samples from different origins and different parts

[0057] The current Chinese Pharmacopoeia does not carry out quality control on the sugar components of red ginseng, so the phenomenon of adding sugar (especially sucrose) to red ginseng in the market is increasing, which seriously affects the quality of red ginseng raw materials and related final products. The example of the present invention collects 8 parts of red ginseng from 4 places of production, including samples that may contain sugar and sugar-free samples, and uses near-infrared to quickly measure the content of each index component; in addition, separately collects 1 part of red ginseng reed head and ginseng whiskers , using near-infrared to quickly determine the content of each index component of the sample.

Abstract

The invention discloses a method for rapidly determining the respective content of water, carbohydrate components and ginsenoside of red ginseng by using a near infrared diffuse reflection spectrum. The method comprises the following steps: carrying out a routine analysis process to obtain the references of all quality control index components in red ginseng samples and obtain near infrared spectrum data of all red ginseng powder samples, carrying out mathematical modeling to make all the routine analysis references of the index components and the near infrared spectrum data compose a database, and carrying out modeling optimization by using a full factor test analysis process to respectively obtain quantitative correction models of all the indexes; and collecting the near infrared spectrum of an unknown red ginseng powder sample, and determining the content of every index component by using the quantitative correction models. The method has the characteristics of rapid and simple analysis, no pollution in the analysis process, and simultaneous determination of various index components, and allows whether sugar is added or not to be rapidly discriminated especially through determining the carbohydrate components in order to maximally guarantee the quality of the red ginseng.

Description

technical field [0001] The invention relates to the field of medical analysis and detection, in particular to the simultaneous rapid determination of the contents of multiple red ginseng powder quality indicators by using near-infrared diffuse reflectance spectroscopy. Background technique [0002] The quality index of Chinese Pharmacopoeia (2010 edition) red ginseng is mainly moisture and ginsenoside Rg1, Re and Rb1, and wherein moisture adopts the method detection of drying weight loss, and this method is more time-consuming; The detection of ginsenoside adopts high-performance liquid chromatography, and this method Sample pretreatment involves steps such as Soxhlet extraction, ultrasonic extraction, evaporation to dryness, and reconstitution. The entire analysis process is cumbersome; at the same time, the organic solvents used in the analysis will pollute the environment and are not conducive to human health. [0003] Near-infrared spectroscopy has the advantages of simp...
