摘要
对于米糖中γ -谷维醇的测定方法———HPLC法和紫外分光光度法进行了深入研究 ,并着重对紫外分光光度法回收率、样品处理、提取溶剂、提取时间、光作用等各种影响因素进行了探讨 ,该方法操作方便 ,仪器简便 ,测定成本低 。
Two methods of determining γ Oryzanol in rice bran——HPLC and ultraviolet spectrometry were studied deeply.The factors in ultraviolet spectrometry method including sample treatment,solvent selection,extracting time and light stabilization of γ Oryzanol ethanol solution were mainly investigated.The ultraviolet spectrometry is very suitable for industry production due to its conveniently operation,lower costing and reliability.
