An RP-HPLC separation of CF together with catechins in green tea was developed by Goto et al. (280) and carried out on a Develosil ODS-HG column with a gradient water-ACN-phosphoric acid elution. The DLs were about 0.2 ng for the nine analytes. 

Tea leaves (Camellia or Thea sinensis, Theaceae) contain cyanidin 3-glucoside (34) and other anthocyanins. Phenolic materials make up as much as 30% of the dry weight of fresh tea leaves (Pierpoint, 1986 Sanderson, 1972). The five major catechins in green tea are (-f-)-catechin (64) (Fig.
