Vitamin C contents were investigated in 14 tea brands collected from local market in Peshawar and one brand from National Tea Research Centre at Mensehra, NWFP Pakistan, using UV-Visible Spectrophotometry. In all tea samples, high amount of Vitamin C was found in green tea than black tea leaves. The fresh tea leaves collected directly from plant was found to have the same amount of Vitamin C as the green tea leaves. The small amount of vitamin C in black tea may be due to its processing as vitamin C is highly sensitive top heat, light and decomposes frequently.
