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 Zeeland using terahertz time-domain spectroscopy, which includes the following steps:
[0031] 1), sample preparation: the sample used is the full-component traditional Chinese medicine Zeilan granule produced by Beijing Kangrentang Pharmaceutical Co., Ltd., weigh about 60 mg of Zeilan granule with an electronic balance, and then grind it into a fine powder in a mortar. Next, set the shape in the tablet press, increase the pressure to 5 tons, and take 8 minutes to obtain a disc with a diameter of 13 mm, smooth on both sides, and a thickness of less than 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 empty sample rack into the sample compartment in t...

Abstract
The invention relates to the field of detection of traditional Chinese medicinal materials, in particular to a method for detecting full-ingredient Chinese herbal medicine herba lycopi granules on the basis of a terahertz spectrum technology. The invention aims to provide the detection method, in the method, a wide-frequency-band terahertz spectrum technology is used to represent full-ingredient Chinese herbal medicine granules, so as obtain fingerprint peaks of the full-ingredient Chinese herbal medicine granules in the wide frequency spectrum band, and different types of full-ingredient Chinese herbal medicine granules are distinguished according to the characteristics of the terahertz fingerprint peaks in the wide frequency spectrum band. By adopting the method, the problems about the spectrum characterization and category distinguishing for measurement of the full-ingredient Chinese herbal medicine granules are solved, assistance of chemical agents is reduced, and the method is a purely physical detection method; the method is simple in operation, rapid 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 Eupatorium eupatorium in full-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 ...
