Abstract

Introduction

Microwave-assisted extraction (MAE) is a highly efficient technique used to extract bioactive compounds from plant materials. This method is gaining popularity due to its alignment with the principles of sustainable and green chemistry. Microwave radiation selectively heats polar molecules and their solvents, leading to a rapid increase in temperature within the sample.

Methods

The MAE method can be performed solvent-free or utilize environmentally friendly solvents (., water, ethanol), thereby reducing environmental pollution. Therefore, the selection of a suitable solvent is the most crucial parameter in an efficient extraction process. Reduced exposure to high temperatures minimizes the degradation of heat-sensitive compounds, resulting in higher-quality extracts.

Results

This process significantly reduces extraction time compared to conventional methods, which typically require longer heating periods. MAE typically yields higher amounts of bioactive compounds in shorter times due to improved cell wall disruption and enhanced solvent penetration.

Discussion

MAE improves atom economy by enhancing extraction efficiency, leading to less chemical waste. This technique minimizes the generation of hazardous substances during the extraction process.

Conclusion

MAE is considered a green and sustainable technology due to its energy efficiency, reduced solvent usage, enhanced extraction yields, and lower environmental impact.
