Gathered leaves were processed to make alluring examples for biochemical examination in the research facility of Branch of Nourishment Engineering and Tea Innovation, SUST. Results uncovered that the basic constituents like dampness, caffeine, polyphenol, lipid, protein, debris, ascorbic corrosive, causticity and pH esteem in green tea produced using diverse matured leaves were found marginally higher than oolong tea, ran from 6.38±1.06 to 3.49±0.59%; 4.91±0.82 to 1.49±0.24%; 30.88±5.15 to 18.23±3.04%; 7.50±1.25 to 9.58±1.59%; 13.15±2.19 to 17.33±2.88%; 3.87±1.65 to 7.86±1.31%; 48.4±8.05 to 21.3±3.55(mg); 2.13±0.68 to 1.18±0.19% and 5.52±0.11 to 5.97±0.18%, individually. Additionally, the dampness, caffeine, polyphenol, lipid, protein, debris, ascorbic corrosive, corrosiveness and pH esteem from various matured leaves were found in oolong tea from 6.19±1.04 to 2.98±0.49%; 4.68±0.78 to 1.11±0.19%; 20.89±3.48 to 8.23±1.37%; 6.40±1.07 to 9.13±1.52%; 13.03±2.17 to 17.19±2.86%; 3.44±0.58 to 7.57±1.27% 6.44±1.08 to 0.98±0.17 (mg); 2.02±0.34to 1.02±0.17% and 5.53±0.11 to 5.97±0.20%, separately.
