Analysis of Phenolic acids in some samples of Indian and Nepal Tea by High Performance Liquid Chromatography
The beneficial effects of tea (Camellia sinensis) leaves have already been studied in detail. However, the scientists are keen to explore the exact scientific reasons for such effects. The biochemical analysis of tea samples has indicated that they contain mostly polyphenols, mainly catechins. Catechins are present in food and beverages of plant origin. Keeping this in view, High Performance Liquid Chromatographic analysis was performed to estimate phenolic acids in 26 samples of tea (samples of Indian market brand, Indian tea garden and Nepal tea garden such as Janhit green teaTM (JGT), Tata tea premiumTM (TT ), Brooke bond TaazaTM (BBTZ), Lipton Darjeeling TeaTM (LDT), Tea cityTM (TCT), Taj Mahal TeaTM (TAJM), Tetley TeaTM (TET), Assam dana (DASM), Assam dana 1 (ASMD-1), Assam dana 2 (ASMD-2), Assam Tea (ASM), North Bengal tea (NB), North Bengal dana-1 (DNB-1), North Bengal-2 (DNB-2), North Bengal Upper (NBUP), Darjeeling tea-FOP (DARJ-FOP), Darjeeling tea-FOP1 (DARJ-FOP1), Darjeeling teabrake (DARJ-br), Indian tea garden (Darjeeling-ITGA (DARJ-ITGA), DarjeelingITGB (DARJ-ITGB), Darjeeling-ITGC (DARJ-ITGC) and Nepal tea garden (KP-33A, KP-16A, KP-9A, KPC6 and KP-C2).
