Subcritical water extraction of alkaloids in Sophora flavescens Ait. and determination by capillary electrophoresis with field-amplified sample stacking
H Wang, Y Lu, J Chen, J Li, S Liu - Journal of pharmaceutical and …, 2012 - Elsevier
The extraction and determination of cytisine, sophocarpine, matrine, sophoridine and
oxymatrine in Sophora flavescens Ait. were performed using subcritical water extraction and
capillary electrophoresis with field-amplified sample stacking. The effects of extraction
temperature, pressure, time and cycle number on the extraction yields were investigated
systematically for accelerated solvent extraction with ethanol (ASE) and accelerated solvent
extraction with water (subcritical water extraction, SWE). The extraction yields obtained …
