The purpose of this study was to describe the simple, rapid, and environmental-cost effective determination method for saikosaponins in complicated samples like Bupleuri radix and traditional Chinese medicines (TCM). Saikosaponin standards, extracts of Bupleuri radix and TCM, were applied to a polyethersulphone (PES) membrane and developed by acetonitrile-water (1:4, by volume). Saikosaponin a (SSa), SSc, and SSd were visually detected by an immunostaining method (called Eastern blotting technique) using a monoclonal antibody (MAb) against SSa. At least 62.5 ng of SSa, SSc, and SSd were clearly detectable individually. These coloring spot areas of saikosaponins on PES membrane were calculated by using the NIH Imaging software and three saikosaponins can be analyzed quantitatively between 62.5 ng and 1.0 microg. Saikosaponins in Bupleuri radix and TCM were determined and these results of SSa and total saikosaponin concentrations were in good agreement with those from the ELISA analysis.
