Abstract:
The newest development of applications of IR techniques to the identification of Chinese herbs, the discrimination of folk medicine herbs, Chinese herbs processing and Chinese traditional injection, which involving enhancing computer analysis depth, intensifying the pre-treatment of Chinese herb and using 2D-IR correlation spectroscopy for processing control, was elaborated in the present paper. Meanwhile, the establishment of multi-component determination analysis system of chromatographic fingerprint diagram was shown. And the sameness and difference of the IR spectroscopy and chromatography fingerprint diagram techniques were analyzed, and a comparison was made in terms of quality control of Chinese herbal medicine.

Transmittance is defined as the ratio of the radiant power passing through a sample to that from the radiation's source. Multiplying the transmittance by 100 gives the percent transmittance (%T), which varies between 100% (no absorption) and 0% (complete...
