Effect of solvents on phytochemical concentrations and antioxidant activity of Garcinia benthamiana stem bark extracts
The effect of solvents of various polarities (hexane, chloroform, ethyl acetate, and methanol) on phytochemical concentrations and antioxidant activities of stem bark of Garcinia benthamiana were examined. A medium polar solvent, ethyl acetate, was the most efficient in extracting the phenolic compo...
