玉米须总黄酮的提取及鉴别

The Total Flavanone of Corn Silk Withdraws and Distinction

目的为充分利用玉米须植物资源,避免资源的浪费,探讨玉米须总黄酮的提取及鉴别方法。方法采用纯物理的工艺流程过程和分光光度法从玉米须中提取黄酮类物质,对所提取的黄酮类物质进行验证。结果测得样品中总黄酮的含量C=6.45%,回收率为97.9%,其纯度和产率均较高。结论该方法采用全物理过程,无任何化学变化及污染,是提取玉米须黄酮类物质的有效途径。

Objective In order to make use of the resources of corn silk and avoid waste. Methods Use purely physical process flow and spectrophotometry to introduce the method of which withdrawed the flavanone from corn silk, and check the flavanone which withdrawed from corn silk. Results By this method getting the contents of the total flavanone of corn silk is C = 6.45% and rate of the recovery is 97.9%. Conclusion Using this text which provide the withdrawal and purifying methods to get the outcome and purity of the flavanone is all very high . This method is purely physical process, and has no any chemical change and pollution. It is an ideal way to withdraw the flavanone of corn silk.
