The DESs solvent was recovered and recycled at least three times without loss of extraction yields. The DESs of ChCl-Eth had no significant effect on the antioxidant activity of rutin and the recovered rutin has exhibited more antioxidant activity than methanol extract. The selected greens solvents and their extracts did not show cytotoxic activity against the human embryonic kidney cell line (HEK-293A).
