3.2.5. Number of extraction cycles
Furthermore, the impact of extraction cycle was studied in thisexperiment. When the powders of S. baicalensis were continuouslyextracted 3 times, the total amount was defined as 100%. FromFig. 2e, it was found that the extraction effect for the first time hadreached more than 90%, and marginally augmented with increas-ing of the number of extraction cycles. Therefore, in order to reducethe waste of resource, energy and time, only one extraction wasselected.
