Impact of amine- and phenyl-functionalized magnetic nanoparticles impacts on microwave-assisted extraction of essential oils from root of Berberis integerrima Bunge

In this study, essential oils were extracted from the roots of Berberis integerrima Bunge using hydrodistillation (HD) and modified microwave-assisted hydrodistillation (MAHD) techniques for the first time. In the first step, amine- and phenyl-functionalized magnetic nanoparticles were synthesized through the silanization method. Afterwards, their effects on extraction efficiency were investigated from quantitative and qualitative points of view. The results obtained from the conventional HD method explicitly showed that the quantity of the extracted essence was negligible both in the presence and absence of modified synthesized nanoparticles but, the extraction yield was significantly increased through the MAHD method, particularly in the presence of the modified magnetic nanoparticles, as extraction yields were 0.16, 0.61 and 0.71 w/w% and chemical diversity of 10, 10 and 18 compounds were obtained from MAHD, MAHD with modified anyl, and with modified phenyl magnetic nanoparticles, respectively.
