Metabonomic Investigation on Rats’ Dynamic Responses to Cantonese Herbal Tea Intake

Abstract

GC-MS-based metabonomics was applied to investigate the urinary metabolic response to Cantonese Herbal tea (CHT) intake during a 38-day-period. Orthogonal projection on latent structures discriminant analysis (OPLS-DA) with student’s t-test revealed that the global characterization of metabolic changes at each sampling time point were different. Dynamic sampling made it possible to evaluate dynamic metabolic responses to CHT intake.
