their beneficial effects.Due to, it tea has attracted considerable interest (Row E?9 Jin, 2006). Phenolic compounds
which constitutes up to 30% on a dry weight basis of fresh tea leaves are water soluble so can be easily extracted
with water, where extraction conditions such as time, temperature, pH, ratio of solvent to material and number of
extraction step variously influenced the obtained extract
