Abstract

The invention discloses a method for near-infrared detection of the mass content of miscarriage-prevention pills. The method comprises the following steps of dissolving the miscarriage-prevention pills by using methanol, and filtering to obtain filtrate which is a test solution; carrying out near-infrared spectrum detection on the miscarriage-prevention pills and measuring the concentration of effective components in the corresponding test solution by high performance liquid chromatography; selecting a reasonable modeling near-infrared spectrum data area, and establishing a corresponding relation between the near-infrared spectrum data and the concentration of the effective components in the test solution; by utilizing the established corresponding relation, carrying out infrared spectrumdetection on the miscarriage-prevention pills to be detected to realize measurement for the concentration of the effective components in the miscarriage-prevention pills to be detected. Compared withthe HPLC (High Performance Liquid Chromatography), near-infrared spectroscopy is simpler and faster in operation, is suitable for content measurement of large-batch miscarriage-prevention pills, can meet the needs for large-scale sample information acquisition in industrial production and plays an important role in controlling the stability of a final preparation product.

Description

technical field [0001] The invention relates to a detection method for Antai Pills, in particular to a method for detecting the mass content of Antai Pills by near-infrared. Background technique [0002] Near-infrared spectroscopy analysis technology is widely called green analysis technology, which has the following unique advantages: fast analysis speed, high analysis efficiency, simple but environmentally friendly analysis process, no need for sample pretreatment or less treatment. Near-infrared spectroscopy is an indirect analysis method for qualitative or quantitative analysis of unknown samples by establishing a calibration model. The analysis process mainly includes: collecting samples, collection and preprocessing of near-infrared spectra, establishment and verification of calibration models, For predicting unknown samples, quantitative analysis also includes chemical analysis of sample standard values. [0003] In the field of traditional Chinese medicine quality c...
