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] This embodiment provides a method for detecting hot dog ridges using terahertz time-domain spectroscopy, which includes the following steps:

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

[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 Chinese herbal medicine detection, in particular to a method for detecting full ingredient granule Chinese herbal medicine scalded woodwardia japonica based on a terahertz spectrum technology. According to the method, the wide frequency band terahertz spectrum technology is utilized to represent full ingredient Chinese herbal medicine granules, fingerprint peaks in the wide frequency band of the full ingredient Chinese herbal medicine granules are obtained, and the full ingredient Chinese herbal medicine granules of different varieties are identified by utilizing the terahertz fingerprint peaks in the wide frequency band. According to the method, the measurement of spectral characterization and variety identification of the full ingredient Chinese herbal medicine granules are achieved, the assistance of chemical reagents is reduced, and the method is a pure physical detection method. The method is simple to operate and has accuracy in data processing, and results are accurate.

Description

technical field [0001] The invention relates to the field of detection of traditional Chinese medicinal materials, in particular to a detection method of Chinese herbal medicine hot dog ridge 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 often used to describe the ...
