Anthocyanins can be used as natural pigments and health-promoting components. The extraction methods of obtaining those phytocompounds are of particular interest. Therefore, the objective of the presented study was to evaluate the possibility of using water-glycerol systems for the acquisition of anthocyanin extracts from fruits of black chokeberry and from elderberry fruits. Glycerol is characterised by a lower polarity compared to water, due to which its presence enhances the efficiency of extraction of anthocyanins from the plant material. It was demonstrated that the highest concentration of anthocyanins was obtained for a water-glycerol system with 50 % glycerol concentration, at extraction temperatures of 20°C and 50°C. The extraction system with 65 % glycerol content was optimal in the case of extraction conducted at temperature of 80°C. The study showed that glycerol can be an alternative solvent in the extraction of anthocyanins, replacing e.g. ethanol which for various reasons cannot always be used in food products, due to e.g. age or health-related limitations.

花青素可用作天然色素和促进健康的成分。获得那些植物化合物的提取方法特别令人关注。因此，本研究的目的是评估使用水甘油系统从黑苦莓果实和接骨木浆果果实中提取花青素提取物的可能性。甘油的特征是与水相比极性较低，因此，甘油的存在增强了从植物材料中提取花青素的效率。结果表明，在20°C和50°C的萃取温度下，甘油浓度为50％的水-甘油体系的花青素浓度最高。在80°C的温度下进行提取的情况下，具有65％甘油含量的提取系统是最佳的。
