| Abstract: | Objective] The study aimed to explore the optimum conditions for extracting ergothioneine from mushroom handle of Agaricus bisporus.Method] Ergothioneine was extracted from the mushroom handle of Agaricus bisporus by alumina column chromatography.The feed volume,elution buffer,ethanol concentration,sample pH and elution rate were optimized with recovery rate and purity as indicators.Result] The optimum extraction conditions are as follows:feed volume;20 ml;elution buffer,70% ethanol;sample pH,9.0;and elution rate,2 ml/min.Under the above conditions,the recovery rate and purity were 91.2% and 25.6%,respectively.Conclusion] This study provides a new way and method for comprehensive utilization of processing wastes of Agaricus bisporus. |
