Development of a New Binary Solvent System Using Ionic Liquids as Additives to Improve Rotenone Extraction Yield from Malaysia Derris sp.

Figure 3

Visualization of rotenone migration markers of five different types of binary solvent systems used at 14 hrs of extraction. The markers were visualized on the alumina-based TLC plate under UV light of 254 nm. (a) Acetone; (b) [BMIM] Cl; (c) [BMIM] Oac; (d) [BMIM] NTF2; (e) [BMIM] OTF; and (f) [BMP] Cl. The dark circled markers of STD and R (R1, R2, and R3) represent the rotenone standard and replication of each binary solvent systems used.
