The extraction of ecdysterone(ECD) and total phytosterone from Adiyranthes bidentata with different methods was studied in this paper, and optimized the extraction technics conditions with different optimizing ways.
In the process of supercritical fluid extraction ECD from Achyranthes bidentata, the flow rate of CO_2 was 2L/min, static extraction time was 10min. The kind of modifier, flow rate of modifier, extraction pressure and temperature were studied first, the preliminary optimum conditions...
