Abstract

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).

高效液相色谱法分析印度和尼泊尔茶中酚酸的含量

茶(Camellia sinensis)叶子的有益作用已经被详细研究过。然而，科学家们热衷于探索这种影响的确切科学原因。茶叶样品的生化分析表明，它们主要含有多酚，主要是儿茶素。儿茶素存在于植物性食品和饮料中。保持这个观点,进行高效液相色谱分析,估计茶酚酸在26个样本(样本的印度市场品牌,印度茶园和尼泊尔等茶园Janhit绿色teaTM (JGT),塔塔茶叶premiumTM (TT),布鲁克债券TaazaTM (BBTZ),立顿大吉岭teaTM (LDT),茶cityTM (TCT)、泰姬陵teaTM (TAJM),泰特莱teaTM(春节),阿萨姆邦达纳(DASM),阿萨姆邦dana 1 (ASMD-1),阿萨姆邦dana 2 (ASMD-2),阿萨姆茶(ASM),北孟加拉茶(NB),北孟加拉丹那-1 (DNB-1)，北孟加拉-2 (DNB-2)，北孟加拉上(NBUP)，大吉岭茶- fop (DARJ-FOP)，大吉岭茶- fop1 (DARJ-FOP1)，大吉岭茶树(DARJ-br)，印度茶园(大吉岭- itga (DARJ-ITGA)，大吉岭itgb (DARJ-ITGB)，大吉岭- itgc (DARJ-ITGC)和尼泊尔茶园(KP-33A, KP-16A, KP-9A, KPC6和KP-C2)。
