Abstract: Bymeans ofOrthogonal test,theoptimumconditions forsoyban isoflaveo neglycosidetobehydrolyzedinto isoflavoneaglyconwerefound,asfo llows:concentration ofmethanolofmuriaticacid,2mol /L;temperature,80℃;and time ,60min.The sample before gydro lyzationcontainedD,13.86%,G,23.48%,De,0.22%and Ge,0.02%.The sample after hydrolyzation contain ed D,nd G,nd De,14.01%,and Ge,23.45%.It could be concludedthat the hy-drolyzation reaction was complete .
