In this study, tanshinones were selected as target compounds to evaluate the performance of this extraction method. Factors affecting the extraction efficiency, such as the duration, IL concentration and solid/liquid ratio were systematically optimized using the response surface methodology.
the power of ultrasound, there are some other factors affecting the extraction efficiency, including the concentration of solvent, extraction temperature, and ratio of solvent to solid (Setyaningsih et al., 2019). Therefore, those factors require optimization to obtain extract with the optimum antioxidant activity.
What are the factors affecting the oil extraction effect? 1. Solvent oil extraction temperature. The solvent extraction temperature has a great influence on the oil extraction rate. With the increase of extraction temperature, the viscosity of oil and solvent decreases, and the thermal movement of molecule increases, so the extraction speed is ...
Type and percentage of solvent used for extraction, nature of the leaves, leaf conditions, time of harvesting, acidification percentage and its type, drying temperature and storage temperature are the major factors affecting extraction of polyphenols [4].
