Abstract:
Objective: A method for identification of root cortex and woody core of Morindae Officinalis Radix (MOR) was established based on Ultra Performance Liquid Chromatography (UPLC) characteristic chromatogram and chemical pattern recognition technique. Methods: Using UPLC technique, the characteristic chromatograms of iridoids and oligosaccharides of root cortex and woody core of MOR were established, combined with the similarity analysis, variance analysis, cluster analysis, principal component analysis (PCA) methods for chemical pattern recognition research. Results: The UPLC characteristic chromatograms of iridoids and oligosaccharides of different parts of MOR were established, and 12 and 20 common characteristic peaks were confirmed, respectively. The UPLC characteristic chromatograms of root cortex and woody core of MOR were obviously different. Conclusion: UPLC characteristic chromatograms of iridoids and oligosaccharides of MOR combined with chemical pattern recognition analysis method can reflect the difference of root cortex and woody core of MOR integrally, comprehensively and truly, which provides more sufficient basis for the necessity of removing woody core from MOR.
