Problems solved by technology

Among the above six methods, the first three methods are simple and easy to implement, less costly and shorter in time, but the accuracy and reproducibility are poor
Thin-layer chromatography qualitative and semi-quantitative identification methods have high qualitative accuracy, but quantitative accuracy is average, time-consuming, and poor reproducibility
The accuracy and reproducibility of HPLC fingerprint qualitative and quantitative identification and HPLC-MS qualitative and quantitative identification are good, but the method is more complicated, takes a long time, consumes a lot, and is not suitable for rapid detection. In addition, the instrument Equipment requirements are relatively high

Abstract

The invention provides an infrared spectrum detection method of ginseng and astragalus injection liquid, which comprises the following steps: a. processing injection liquid samples; b. drawing maps; c. carrying out standard control; d. comparing the maps; and e. obtaining the conclusion: observing whether the ginseng and astragalus injection liquid to be detected conforms to the specification of the standard or not through the comparison and whether the maps conform to the standard maps obtained from the standard ginseng and astragalus injection liquid samples or not, and further obtaining the conclusion. The ginseng and astragalus injection liquid with the feature peak near 779, 818, 867 and 1056 and the similarity between 0.98 and 1.00 is selected as qualified products. The invention uses the macroscopical fingerprint performance of the infrared spectrum, the variation features of the infrared spectrogram is directly used on the quality control, or can be directly used on the quality control after digital processing, and the infrared spectrum technology is sufficiently utilized for fast monitoring the quality of the ginseng and astragalus injection liquid, including the stability, the ingredient variation, the adulteration, the impurities, unpredictable quality problems and the like of the ginseng and astragalus injection liquid.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicine detection, and in particular relates to an infrared spectrum detection method of Shenqi injection. Background technique [0002] The main components of Shenqi injection are Codonopsis pilosula and Radix Astragali; it is prepared by the water extraction and alcohol precipitation method commonly used in traditional Chinese medicine preparations; it has the effect of nourishing qi and strengthening the body; it is used for the adjuvant treatment of lung cancer and gastric cancer with qi deficiency syndrome, and it can be used in combination with chemotherapy to improve the curative effect , Protect the blood, improve the immune function of patients with qi deficiency, improve the symptoms of qi deficiency and improve the quality of life. At present, the quality control methods of the injection include the following: visual observation of the color and properties of the injection,...
