Abstract

To date, many studies have been published, aiming to extract bioactive compounds from plants. Lately, research focuses on maximizing the extraction yield, using environmentally friendly techniques and solvents. In this study, the extraction of polyphenolic compounds from Cistus creticus is discussed. Extraction of the compounds has been carried out with water and ethanol, employing the most common approach. To further enhance the extraction yield, the usage of four deep eutectic solvents (DESs) has also been examined. In an effort to further enhance the extraction yield, pulsed electric fields have also been employed. According to the results, it was evident that the use of DESs made of glycerol: choline chloride (2:1) increased the extraction yield by 75%, compared to extraction with water. Moreover, the use of pulsed electric fields enhanced the extraction yield of the common approach, by up to 70%. When pulsed electric fields and DESs were combined, the extraction yield increased by 14%, compared to the use of DESs only. Finally, the extract was analyzed for its content in volatile compounds, and it was found that new compounds could be extracted with the use of DESs.

深共晶溶剂和脉冲电场法提取山茱萸中多酚类和挥发性化合物

迄今为止，已经发表了许多旨在从植物中提取生物活性化合物的研究。近年来，研究的重点是最大限度地提高提取率，使用环保的技术和溶剂。本研究主要对山茱萸中多酚类化合物的提取进行了研究。采用最常用的方法，用水和乙醇进行了化合物的提取。为了进一步提高萃取率，研究了四种深共晶溶剂(DESs)的使用。为了进一步提高萃取率，还采用了脉冲电场。结果表明，使用甘油:氯化胆碱(2:1)制备的DESs，与用水提取相比，提取率提高了75%。此外，脉冲电场的使用提高了普通方法的提取率，最高可达70%。当脉冲电场和DESs结合使用时，与仅使用DESs相比，提取率提高了14%。最后对提取液的挥发性化合物含量进行了分析，发现利用DESs可以提取新的化合物。
