Abstract

1 The chlorophyll a and chlorophyll b content of 75 samples of green, oolong and black tea have been determined by a spectrophotometric method. 2. The average total chlorophyll content of the green teas examined was 1.39 mg./gm. Comparable figures for oolong and black teas were 0.82 mg/gm and 1.01 mg./gm respectively. 3. The percentage of chlorophyll a averaged 81.1 per cent in green teas, 78 5 per cent in oolong teas and 70 9 per cent in black teas.
