Abstract: The natural UV radiation is one of the environmental factor to upregulate qualities of the tea. Tea grown in the North Bengal area starting from high altitude Darjeeling to the Himalayan foothills to Dooars and Terrai region including Darjeeling, Jalpaiguri and Siliguri, are exposed to different doses (Irradiance) of natural UV radiation. Such UV radiation can upregulate the secondary active metabolites like polyphenols viz. catechin, gallic acid etc. These up-regulated secondary metabolites contribute to the elevated therapeutic qualities like antioxidant and antimicrobial properties. Different types of solvents like aqueous, methanol and ethanol can extract different contents of active metabolites which can be further continued towards the drug designing process. Here the Dooars and Terrai grown (Low altitude grown) teas are having less antioxidant and antimicrobial potentials and active components than high altitude grown Darjeeling tea.
