Characterization of the constituents and antioxidative activity of cocoa tea (Camellia ptilophylla)

► White cocoa tea (WCT), green cocoa tea (GCT), black cocoa tea (BCT) (all derived from Camellia ptilophylla) were prepared. ► The total polyphenols in 3 types of cocoa tea and 4 common teas follow this order: WCT > GCT > Blc > Lj > BCT > Yh9 > Qmh. ► EGCG was the major catechin in commercial green tea samples. While in WCT and GCT, the major catechin was GCG. ► The antioxidative activity of the seven tea samples followed this order: WCT > GCT > Blc > Lj > BCT > Yh9 > Qmh.
