Kinetics and model building on ultrasonic extraction of schisandrin from fruit of Schisandra chinensis

Abstract

The kinetics of the extraction schisandrin of Schisandra chinensis was investigated. Based on the assumption of a second-order mechanism for the extraction, a conventional extraction model and an ultrasonic extraction model were developed to predict the extraction rate constant, the extraction capacity, and the initial extraction rate with various temperatures and ultrasound powers. © 2012 Wiley Periodicals, Inc.
