Full-ingredient Chinese herbal medicine rhizoma typhonii granule detection method based on terahertz spectroscopy technology

Abstract

The invention relates to the field of Chinese herbal medicine detection, in particular to a full-ingredient Chinese herbal medicine rhizoma typhonii granule detection method based on the terahertz spectroscopy technology. According to the detection method, full-ingredient Chinese herbal medicine granules are represented through the wide-frequency-band terahertz spectrum technology, fingerprint peaks within the wide frequency spectrum band are obtained, and full-ingredient Chinese herbal medicine granules in different categories are distinguished through the characteristics of the terahertz fingerprint peaks within the wide frequency band. The method solves the problems about measurement of spectrum representation of the full-ingredient Chinese herbal medicine granules and category distinguishing; assistance of chemical reagents is reduced, and the detection method is a pure physical detection method; the method is easy to operate, high in data processing speed and accurate in result.

Description

technical field [0001] The invention relates to the field of detection of traditional Chinese medicinal materials, in particular to a detection method of the Chinese herbal medicine Aconite Radix in full-component granules based on terahertz spectroscopy. 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 u...

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.
