Ultrasonic circulating extraction (UCE) approach was developed for effective extraction of orientin and vitexin from the flowers of Trollius chinensis successfully. In this study, some parameters potentially influencing the yields of orientin and vitexin were systematically investigated and optimized by Plackett–Burman and Box-Behnken design, and the optimum operational conditions obtained were 60%...
In this study, ultrasonic circulating extraction (UCE) technique was firstly and successfully applied for extraction of samara oil from Acer saccharum. The extraction kinetics were fitted and described, and the extraction mechanism was discussed. Through comparison, n-hexane was selected as the extraction solvent, the influence of solvent type on the responses was detailedly interpreted based on the...
