Objective:To optimize the Preparation of bioactivity part of total isoflavone aglycones of Iris tectorum Maxim..Methods:The optimum absorption conditions of AB-8 macroporous absorption resin is studied by orthogonal design,and eluted with a gradient of EtOH in H2O to obtain glycosides and aglycones,glycosides were hydrolyzed by acid,the acid was eliminated by macroporous absorption resin.Results:The total isoflavone aglycones' purity have 59%~63%,yield 3.59%.Conclusion:The preparation is simple,convenient and reliable,and is suitable for utilization of industry.
