Yield of rotenone, % (w/w) in dried roots with respect to five different types of binary solvent systems. —[BMIMI] OTF + acetone is the best binary solvent system to procure the highest rotenone content in dried roots () at the optimum time of extraction process (14 hrs). Error bars represent the standard deviation (SD) of triplicates ().
