Abstract
Green tea catechins (GTCs), namely (-)-epigallocatechin gallate (EGCG) and epicatechin gallate (ECG), were analysed in 25 prominent Indian tea cultivars cultivated in North, South and North-east states of India using an optimized procedure of extraction and HPLC determination. Kangra Jawala grown in Palampur (North India) showed the highest content of EGCG (6.88%), followed by TRI-2026 (6.83%) grown in Coonoor (South India) and lowest content were recorded in P-126 (1.2%) grown in Darjeeling. The TV-1 cultivars from Palampur showed the highest content of ECG (2.74%)among all the samples analysed.
