Microwave assisted extraction of phytochemicals an efficient and modern approach for botanicals and pharmaceuticals

ABSTRACT

The final quality of pharmaceutically active herbal preparation is significantly contributed by extraction procedures. Hence in the last decade Microwave assisted extraction [MAE] has been introduced. This is an efficient and modern tool with multiple benefits as compared to the traditional methods of extraction. The benefits are in terms of reduction in cost, time of extraction, amount of solvent used, energy consumptions and low CO2 emission. Therefore present study was planned to give brief overview on applications of microwave assisted extraction of natural products. It is also discussed that how the various parameters of microwave assisted extraction like nature of the solvent, temperature, particle size, power level of microwaves and time of irradiation influences the extract yields of plant parts. This review also emphasizes the application of MAE for increased production of phyto-medicines, sweeteners, spices and all other commercial products related to botanicals
