*11.2.2.1 Total phenolic content*

Calibration curve of standard gallic acid showed linear equation at y = 0.014x + 0.395, R2 = 0.996 The content of phenolics in different solvents was as 25.73 ± 0.21, 42.09 ± 0.19 and 63.76 ± 0.29 mg GAE/g for chloroform, ethanol and ethyl acetate respectively. As compare to other solvent ethyl acetate gave more yields hence this is suitable solvent for extraction of phenolics.
