A study was carried out to determine a procedure for producing high yield of bioactive flavonoids from Mimosa pigra as antioxidant. Various parts of Mimosa pigra were extracted using various solvents such as methanol, 80%
methanol, ethanol, 70% ethanol and ethyl acetate in two ways: (1) eluted in the solvents overnight; (2) boiled the Mimosa pigra in the solvents for l-2 hours and
left it overnight.
