Abstract

A new extraction technique, ionic liquid-assisted extraction (ILAE), has been developed. The ILAE process was further optimized by varying different parameters such as pretreatment time and temperature, ionic liquid/sample ratio, particle size and solvents. Under the optimum conditions, the extraction yield of ILAE was higher than that of Soxhlet extraction. The results of bioassay test showed that crude extract of ILAE was almost the same with that of Soxhlet extraction. The results in this study can serve as a reference for the ILAE of effective constituents in medicinal plants.
