Microwave-assisted extraction of antioxidative anthraquinones from roots of Morinda citrifolia

This study demonstrated promising results for microwave-assisted extraction (MAE) of antioxidative anthraquinones from roots of a medicinally important plant, Morinda citrifolia. The effects of temperature, ethanol compositions, and types of solvents on the percent recovery of the extract were determined. The extraction recovery and the antioxidant activity of the extract were compared with those of the extracts obtained from the conventional...
