Abstract
⺠Antioxidant phenolic compounds were extracted from spent coffee grounds (SCG). ⺠The used methanol concentration and solvent/solid ratio affected the extraction. ⺠Use of 60% methanol at 40 ml/g SCG was established as the best extraction condition. ⺠A phenolic-rich extract (16 mg GAE/g SCG) with FRAP of 0.10 mM Fe(II)/g was produced. ⺠Flavonoids, chlorogenic acid, and protocatechuic acid were present in SCG extracts.
