Abstract
Microwave-assisted extraction (MAE) technology, as an emerging extraction method, has demonstrated significant advantages in the extraction of active components from traditional Chinese medicines. Conventional extraction methods suffer from drawbacks such as long extraction times, large solvent consumption, and low efficiency. In contrast, MAE technology leverages the unique interactions between microwaves and materials to achieve rapid and efficient extraction. This study aims to investigate the application effects and optimization conditions of MAE technology in the extraction of traditional Chinese medicines. By selecting multiple representative herbs as research subjects, a combination of single-factor experiments and orthogonal experiments was employed to systematically examine the influence of microwave power, extraction time, liquid-to-solid ratio, and other factors on the extraction yield of active components. The results indicate that compared with traditional extraction methods, MAE technology can achieve higher extraction yields within a shorter period while better preserving the active components and minimizing impurity introduction. Additionally, this technology features simplicity in operation, ease of control, and environmental friendliness. Further research shows that by optimizing MAE conditions, personalized extraction schemes can be developed for different herbs, thereby enhancing extraction efficiency and product quality. This study not only provides theoretical support and technical guidance for the application of MAE technology in the extraction of traditional Chinese medicines but also offers new insights into the modernization of traditional Chinese medicine processing, promoting technological upgrades and development in the industry.
