Abstract

OBJECTIVE

To prepare tea pigments.

METHODS

Tea pigments are prepared by solvent extraction from Sri lanka black tea.

RESULTS

Tea pigments contains the components as follows: caffeine 1.77%, epigallocatechin 1.37%, catechin 1.20%, epicatechin 9.55%, epigallocatechin gallate 10.52%, epicatechin gallate 9.94%, theaflavin 10.34%, theaflavin monogallate 9.57%, theaflavin digallate 4.81%, thearubigin about 40.93%.

CONCLUSION

The best proportions of the compound that are obtained with HPLC analysis.
