Concentration of rotenone (mg/mL) with respect to five different types of binary solvent systems. —[BMIMI] OTF + acetone is the best binary solvent system to procure the highest rotenone concentration (mg/mL) at the optimum time of extraction process (14 hrs). —[BMIMI] NTF2 + acetone and acetone extract produced high concentration as compared to the [BMIM] Oac, [BMP] Cl, and [BMIM] Cl. Error bars represent the standard deviation (SD) of triplicates ().
