DPPH (150µl) was added to 3ml of methanol and absorbance was noticed immediately at
516nm for control reading. Different concentrations of test samples i.e 25 µl, 50
µl, 100 µl, 150 µl, 200 µl and 250 µl were taken and each of the samples was diluted
with methanol up to 3ml, to it 150 µl DPPH was added.
