Total polyphenols, catechin profiles and antioxidant activity of tea products from purple leaf coloured tea cultivars

► Tea products from green and purple leaf coloured cultivars were analysed. ► Unaerated (green) tea products contained higher levels of TP, catechins and AA. ► Purple tea cultivars also contain catechins and have lower caffeine levels. ► Antioxidant activities of the purple teas were attributed to the anthocyanins. ► Anthocyanins are highly soluble in water than methanol.
