The anthocyanidin fractions in the processed unaerated and aerated tea products derived from the purple coloured tea clones
were identified and quantified by HPLC using pure anthocyanin standards. The order of elution of the anthocyanidin standards
was as follows; cyanidin-3-O-galactoside < cyanidin-3-O-glucoside < delphinidin < cyanidin < pelargonidin < peonidin < malvidin. A representative HPLC chromatogram of aerated tea from a purple tea clone is presented in Fig. 3.
