Fig. 3From: Application of metabolomics to drug discovery and understanding the mechanisms of action of medicinal plants with anti-tuberculosis activityPrinciples of metabolomics: the biological samples of interest are prepared to stop the metabolism (quenching) and the metabolites are collected. The data can be acquired by different analytical methods. The most common are NMR and Chromatography–MS. The data are processed and statistically analyzed. The metabolites resulting from any fluctuation are identified and biological interpretation gives the meaning of the resulting changeBack to article page
