Authentication of Traditional Chinese Prescriptions Using Comprehensive 2D-LC
17 April 2015

The authentication of Chinese herbal medicine (CHM) is a challenging task, a fact that can be attributed to the highly complex nature of plants and preparations used in CHM and the natural variability of the individual plants. As an example of the analysis of a traditional Chinese prescription, this application note shows the comprehensive 2D-LC analysis of Si-Wu-Tang as well as of the individual herbs contained in Si-Wu-Tang. For each herb, characteristic component peaks are selected, and a template is created. The templates are matched to the peaks detected in Si-Wu-Tang to investigate the possibility to detect characteristic components of the individual herbs in a traditional Chinese prescription.
