摘要: 将核桃仁隔膜用50%乙醇回流2h,每次回流体积为100ml,回流两次,用芦丁标准品作参照,硼酸-柠檬酸为显色剂,以410nm作为测定波长,用正交设计法来确定测定最佳条件。测定核桃仁隔膜中黄酮苷含量为0.15mg/ml,回收率为84%~114%。

Abstract: The walnut septum was refluxed twice for two hours each with 100 ml 50% ethanol. With rutin as reference and boric citric acid was taken as developer, at 410 nm wavelength and the optimum conditions were determined by orthogonal design method. The flavone glycoside content in walnut benevolence is 0.15 mg/ml and recover rate 84%~114%.

Key words: walnut septum, flavone glycoside, boric acid-citric acid, orthogonal design method
