Abstract: | A rapid and efficient microwave-assisted extraction (MAE) process for the selective extraction of embelin from Embelia ribes was developed. Solvent selection, microwave energy input and solid loading were optimized. The rate of extraction and purity
of embelin depended upon the solvent used and exposure time to microwaves. Maximum MAE was achieved in acetone with total
yield of 92% (w/w) embelin with 90% (w/w) purity with 1% (w/v) raw material loading at 150 W power level in 80 s. Non-polar
solvents, such as hexane and dichloromethane, were not effective for the selective extraction of embelin. |
