Problems solved by technology

However, the research objects of these terahertz tests are still limited to the original unprocessed Chinese medicinal materials or herbal medicinal materials. This form of medicinal materials has not been purified, so impurity molecules and other interference factors to the spectrum are very large, and the measurement repetition The correlation and correlation are not high, and in the limited range of 2.6THz, it is difficult to obtain the obvious characteristic fingerprint peaks of Chinese herbal medicines experimentally.

Embodiment 1

[0030] The present embodiment provides a method for detecting Evodia rutaecarpa by terahertz time-domain spectroscopy, which includes the following steps:

[0031] 1) Sample preparation: the sample used is the full-component traditional Chinese medicine Evodia rutaecarpa granules produced by Beijing Kangrentang Pharmaceutical Co., Ltd. Weigh about 60 mg of Evodia rutaecarpa granules with an electronic balance, and then grind them into fine powder in a mortar. Shaping in the tablet press, the pressure is added to 5 tons, and the time is 8 minutes, so that a disc with a diameter of 13 mm will be obtained, both sides are smooth, and the thickness is below 0.4 mm.

[0032] 2), sample test: turn on the laser until the output power is stable, calibrate the light collimation in the optical path; turn on the laptop, set the measurement parameters on the program panel of the terahertz spectroscopy system software, and measure after the laser warms up for one hour; Put the prepared empt...

Abstract

The invention relates to the field of detecting a traditional Chinese medicinal material, particularly to a detection method of a full-component Chinese herbal medicine particulate agent of evodia based on terahertz spectroscopic technique. An object of the invention is to provide wide-frequency-band terahertz spectroscopic technique to characterize full-component Chinese herbal medicine particles; fingerprint peaks in a wide frequency band are obtained; and the full-component Chinese herbal medicine particles with different types are distinguished by utilizing characteristics of the terahertz fingerprint peaks in the wide frequency band. According to the method, the problem of weighing spectroscopic characterization and type distinguishment of the full-component Chinese herbal medicine particles is solved, and an auxiliary of a chemical agent is reduced. The detection method is a pure physical method, and is simple in operation, fast in data processing, and accurate in result.

Description

technical field [0001] The invention relates to the field of detection of Chinese medicinal materials, in particular to a detection method of the Chinese herbal medicine Evodia rutaecarpa in whole-component granules based on terahertz spectroscopy technology. Background technique [0002] Chinese medicine extract is a new product of traditional Chinese herbal medicine combined with modern pharmaceutical technology. Establishing effective analysis, identification and identification methods will help Chinese medicine extract to promote the international market of Chinese herbal medicine. At present, traditional Chinese medicine extracts are usually a single compound or a complex mixture system such as full-ingredient extract granules. Traditional Chinese medicine is a complex mixture system. The advantage of traditional Chinese medicine lies in "multi-armed joint operations", that is, compound prescriptions to treat diseases. The theory of yin and yang and five elements is oft...
