Abstract:
Objective: To trace the content changes of tanshinone ⅡA in the preparing process of Kangchi Capsule. Methods: Exploring the influences of the different extraction, concentration and drying on the extraction efficiency of tanshinone Ⅱ A. Results: The extraction of the percolation with 75% ethanol was better than reflux, drying at 60?C and vacuum distilation was optimum condition. Conclusions: Choosing proper extract, concentration and drying could lower the loss of tanshinone Ⅱ A in the preparing process to a certain extent.
