Introduction to the Application of hyphenated chromatographic techniques in the Study of Chinese herbal compound
色谱联用技术在中药复方研究中的应用

The effects of CMM are based on their chemical composition. And it is important to identify the chemical material basis of CMM by means of high-techniques in the course of CMM modernization. The introduction of hyphenated chromatographic - spectroscopic techniques represented a substantial step-forward for Chinese herbal compound analysis. The hyphenated chromatographic -spectroscopic techniques include GC - M S, GC-FTIR, LC-MS, LC-NMR, tandem LC-NMR-MS-MS, et al. It is of good prospects for the coupling of Micro-HPLC(Capillary HPLC) with multistage soft ionization MS like ion trap (MS"), triple stage quadrupoles(MS-MS) and tandem quadrupole-Tof MS(Q-Tof) by the AP interface (ESI and APCI). The rest of the paper explored LC-MS approach on the study of da-chuan-xiong-fang.
