Extraction of Total Alkaloids from Corydalis saxicola Bunting by the Macroporous Resin

The total alkaloids were extracted from Corydalis saxicola Bunting by macroporous resin.Six different macroporous resins were used for extraction of the total alkaloids and dehydrocavidine by using static and dynamic adsorption-desorption experiments.The specific adsorption capacity and eluting of D101 macroporous resin were comparatively high.The optimum parameters of the purification process were established as the sample concentration of 0.2 g/ml at the absorption ? ow rate of 2 BV/h and with 3 BV of 60% ethanol as the desorption solvent.The contents of total alkaloids in the purifi ed extract were over 60%.
