Introduction: An ionic liquid (ILs) is a new alternative solvent (containing cations and anions) has the physical and specific solutions properties, and also had proven to be a promising substituent of conventional organic solvents are flammable, volatile and toxic in various processes. The ILS application in separating the secondary metabolites compound from Peperomia pellucida (L) Kunth herbaceous can be carried out using microwaveassisted extraction method (MAE). Objective: The aim of this study was to investigate the effect of ionic liquid based microwave-assisted extraction method for attracting the secondary metabolites compound from P. pellucida compared with a conventional solvent for the enrichment of secondary metabolites (especially polyphenols group) and their HPTLC fingerprinting profile. Methods: The herb dried powder extracted by microwave-assisted extraction using an ionic liquid such us 1-Butyl-3-methylimidazolium chloride ([BMIM]Cl), 1-Butyl-3-methylimidazolium Bromide ([BMIM]Br). The obtained extract solution was partitioned using an organic solvent; the extract was evaporated to obtain a dry extract and determination the HPTLC fingerprinting profile. Results: Based on the research results was obtained from the various types of solvents there are differences in the extraction of secondary metabolite.

“…Ionic liquids consist of an organic cation and an inorganic or organic anion and characterise by having high ionic conductivity and high thermal and chemical stability and negligible vapour pressure [163]. They are capable of producing many interactions such as hydrogen bonding, dispersion, ionic exchange, electrostatic and π-π, n-π interactions [164]. They can also increase the stability of nanomaterials.…”

Carbon nanotubes (CNTs) possess unique mechanical, physical, electrical and absorbability properties coupled with their nanometer dimensional scale that renders them extremely valuable for applications in many fields including nanotechnology and chromatographic separation. The aim of this review is to provide an updated overview about the applications of CNTs in chiral and achiral separations of pharmaceuticals, biologics and chemicals. Chiral SWCNTs and MWCNTs have been directly applied for the enantioseparation of pharmaceuticals and biologicals by using them as stationary or pseudostationary phases in chromatographic separation techniques such as high-performance liquid chromatography (HPLC), capillary electrophoresis (CE) and gas chromatography (GC). Achiral MWCNTs have been used for achiral separations as efficient sorbent objects in solid-phase extraction techniques of biochemicals and drugs. Achiral SWCNTs have been applied in achiral separation of biological samples. Achiral SWCNTs and MWCNTs have been also successfully used to separate achiral mixtures of pharmaceuticals and chemicals. Collectively, functionalized CNTs have been indirectly applied in separation science by enhancing the enantioseparation of different chiral selectors whereas, non-functionalized CNTs have shown efficient capabilities for chiral separations by using techniques such as encapsulation or immobilization in polymer monolithic columns.
