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 green fruit using terahertz time-domain spectroscopy, which includes the following steps:
[0031] 1), sample preparation: the sample used is Qingguo granule, a full-component traditional Chinese medicine produced by Beijing Kangrentang Pharmaceutical Co., Ltd., weigh about 60 mg of Qingguo granule with an electronic balance, and then grind it into a fine powder in a mortar, and then 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 empty sample rack i...

Abstract
The invention relates to the field of traditional Chinese medicine detection, in particular to a method for detecting full-ingredient Chinese herbal medicine Chinese olive granules on the basis of the terahertz spectrum technology. Full-ingredient Chinese herbal medicine particles are represented through the wide-frequency-band terahertz spectrum technology, fingerprint peaks in a wide-frequency-spectrum section of the particles are obtained, and the full-ingredient Chinese herbal medicine particles of different kinds are distinguished through features of the terahertz fingerprint peaks in the wide frequency band. The method solves the problem about spectrum representation measurement and variety distinguishing of the full-ingredient Chinese herbal medicine particles, assistance of chemical reagents is reduced, and the method is a pure physical detection method. The method is easy to operate, data processing is quick, and results are accurate.
Description
technical field [0001] The invention relates to the field of detection of Chinese medicinal materials, in particular to a method for detection of green fruits of Chinese herbal medicines in full-component granules based on terahertz spectrum 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 use...
