Increased interest in potential health-protective activities of flavonoid-rich foods has created the need to take advantage of HPLC column and system advances in order to optimize methodologies for flavonoid analysis. Two new RP-C18 methods for HPLC-DAD analysis of tea flavonoids were developed to facilitate separation of catechins within 5 min and separation of catechins and theaflavins within 10 min total analysis time. Catechins were subjected to in vitro gastric and small intestinal digestion. EGCG, EGC, and ECG were significantly degraded at all concentrations tested, with losses of 71–91, 72–100, and 60–61%, respectively. EC and C were comparatively stable, with losses of 8–11 and 7–8%, respectively. HLPCESI-MS/MS indicated that EGCG ...
