Traditional Chinese medicine quality determination system based on near infrared spectroscopy

Abstract

The invention discloses a traditional Chinese medicine quality determination system based on near infrared spectroscopy. The system comprises an extraction tank, a liquid pumping mechanism, a liquid storage cavity, a drawing cavity, a fine adjustment cavity and a detection mechanism, wherein a middle lower part of a side wall of the extraction tank is provided with a conduit in a penetrating and communicating manner, the liquid pumping mechanism comprises a catheter cover detachably connected with a catheter port and a dip pipe penetrating through the catheter cover, a drawing piston is arranged in the drawing cavity in a sealing and sliding manner, a fine adjustment piston is arranged in the fine adjustment cavity in a sealed and sliding mode, a front end of the drawing cavity, a front end of the fine adjustment cavity and the top of the other end of the liquid storage tank are communicated with one another, the detection mechanism comprises a detection container for bearing a to-be-detected sample from a sampling port, a near infrared spectrometer and a detection probe connected with the near infrared spectrometer, the detection probe is used for detecting the to-be-detected sample in the detection container, and the volume of the liquid storage cavity is larger than that of the detection container. The system has advantagest of effectively reducing influence of the liquid medicine in the flow path on detection of the next time period in the detection process of the previous time period.

Description

technical field [0001] The invention relates to the technical field of quality determination of traditional Chinese medicines. More specifically, the present invention relates to a system for measuring the quality of traditional Chinese medicines based on near-infrared spectroscopy. Background technique [0002] Due to the instability and complexity of the source of traditional Chinese medicine, and the fluctuation of working conditions in the actual production process, the consistency of the quality of different batches of extract extracted according to the established process is not good. Therefore, the research and development of a rapid and non-destructive determination method for the content of active ingredients in the extraction process of traditional Chinese medicine will help to solve the quality control problems of key process links in the extraction process, and solve the problems of stability and reliability of traditional Chinese medicine product technology and ...

AI Technical Summary

Problems solved by technology

[0003] Near-infrared spectroscopy has the advantages of easy operation, rich spectral information, fast and accurate analysis, and no sample treatment. It has been widely used in the production process of traditional Chinese medicine preparations in recent years. It is all analyzed by introducing the extract into the bypass, for example, the application number is 201110109187.5, and the patent titled a near-infrared online detection method in the extraction process of traditional Chinese medicine discloses that the pump, filter, and buffer tank are set through the pipeline and in sequence. , flowmeter, etc., introduce the extraction liquid into the flow cell at a certain flow rate, and insert the optical fiber probe into the flow cell for detection. Although it can detect the extraction liquid at intervals, it cannot effectively reduce the detection process in the previous period due to the existence of filters, buffer tanks, etc. The impact of the traditional Chinese medicine liquid in the middle flow path on the next period of detection, thus affecting the near-infrared detection results, or it takes a long time to circulate the pipeline during the detection process to reduce the impact
