摘要：

采用正交试验的方法优化了玉米须黄酮的超声波提取工艺，同时对提取进行了数学模拟。试验结果表明，优化的超声波提取工艺条件为：以50 %的乙醇为提取剂，料液比（g︰ml）1︰84，提取温度75℃，超声波提取时间75 min。此条件下，玉米须黄酮提取率可达1.51 %。与加热浸提法相比，提取时间缩短了25%，提取率提高了约20 %。超声波提取的数学模拟值与试验结果基本吻合。

Abstract:

With an orthogonal experiment, ultrasonic extraction of com silk flavonoids was optimized, meanwhile mathematic simulation was done, The results showed that, the optimum ultrasonic extraction conditions were:50% ethanol, the ratio of material to liquid 1︰84 (g︰ml), the extracting temperature 75℃ and the extracting time 75 min. In these conditions, the extracting rate of flavonoids was 1.51%. Compared with the tradition water extraction method, the extraction time shortens by 25%, the extraction rate increases by about 20%. Mathematical simulation values based on ultrasonic extraction was consistent with experiment values.
