Enrichment of chelidonine from Chelidonium majus L. using macroporous resin and its antifungal activity

Chelidonium majus L. (greater celandine) has been used as an herbal medicine for several centuries. This study investigated an efficient method to purify chelidonine from the extract of C. majus L. using macroporous adsorption resins and evaluated the antifungal activity of chelidonine against Botryosphaeria dothidea as a model strain. Static adsorption and desorption tests revealed that D101 was the optimal resin for chelidonine purification. Pseudo-second-order kinetics model and Freundlich equation model were the most suitable for evaluating the endothermic and spontaneous adsorption processes of chelidonine on D101. Dynamic adsorption and desorption tests on D101 columns showed that the concentration of chelidonine increased 14.16-fold, from 2.67% to 37.81%, with the recovery yield of 80.77%. The antifungal activity of enriched chelidonine products was studied with B. dothidea. The results showed that the EC50 of crude extracts, enriched chelidonine products, and chelidonine standard against B. dothidea were 3.24mg/mL, 0.43mg/mL, and 0.77mg/mL, respectively. The result of antifungal activity test showed that chelidonine had the potential to be a useful antifungal agent. Moreover, the enrichment method of chelidonine was highly efficient, low cost, and harmless to the environment for industrial applications.
