[Infrared spectrum analysis of admixture decoction of herba ephedrae with semen armeniacae amarum].
The infrared spectra of decoction of herba ephedra and semen armeniacae amarum and the mixed decoction of herba ephedra + semen armeniacae amarum were tested. The change in the the mixed decoction was discussed to study the relationship between herba ephedra and semen armeniacae amarum after decoction. The results showed that some absorption peaks of herba ephedra and semen armeniacae amarum were retained in the mixed decoction of herba ephedra + semen armeniacae amarum, such as 1402 and 1076 cm(-1), but some absorption peaks that never appear in the two ingredient spectra increased such as 1394 and 682 cm(-1). New absorption peaks were generated in the mixed decoction of herba ephedra + semen armeniacae amarum, such as 688 and 1187 cm(-1). It can be showed that there were differences in the chemistry environment of the various chemical groups in the three decoctions introduced above, with the variation in absorption peak position, and the biochemical structure of the material changed, possibly with some new chemical compositions created. Medical ingredients in the mixed decoction of herba ephedra + semen armeniacae amarum were not simply the addition of herba ephedra and semen armeniacae amarum based on studies of infrared spectrum of decoction, and the new notion of prescription spectroscopy was proposed.
