[Analysis Case] LC/MS/MS Analysis of Catechin Metabolites in Urine

Qualitative analysis of catechin metabolites in urine, as well as investigation of temporal changes and individual differences.

By using high-sensitivity LC-MS (Q-TOF type), qualitative analysis of low-concentration components such as metabolites in biological samples is possible. It allows for the search for components that have undergone metabolism such as addition or conjugation in the body, as well as inter-sample comparisons aimed at investigating temporal changes and individual differences. After consuming a high-concentration catechin beverage and collecting urine, both unchanged catechin and the metabolite catechin-glucuronide conjugate were confirmed. The amounts of catechin and metabolites in the urine of eight individuals were plotted for excretion over 0.5 to 8 hours post-consumption, and comparisons were made.
