- W2361483567 abstract "Objective To purify sanguinarin and chelerythrine from Eomecon chionantha Hance.Methods Sanguinarin and chelerythrine were extracted from the dry powder of Eomecon chionantha by immersing,supersonic smashing,microwave vibrating,and seeping,respectively,then the alkaloids was separated and enriched using macroporous adsorbent resin.The effects of extracting methods,extracting solvents and eluting solvents on the separation were compared.Results Among the four extracting methods,the immersing extracting and the microwave extracting owned high extraction efficiency.The content of the alkaloids in the seeping extracts was the highest.The content of sanguinarin was 80.10±3.68 mg/g,and that of chelerythrine was 44.31±0.28 mg/g in the seeping extracts,respectively.The extracting efficiency to the alkaloids using hydrochloric acid was higher than that using other acids obviously.The separating effect was optimal using 20%,60%,90% aqueous methanol solution and 100% ethanol as the eluants in turn.Conclusion Seeping extraction is an effective method for separating sanguinarin and chelerythrine from Eomecon chionantha Hance." @default.
