摘要
目的为充分利用龙眼壳植物资源,避免资源的浪费,探讨龙眼壳中总黄酮的提取及鉴别方法。方法采用超声波乙醇浸提法从龙眼壳中提取黄酮类物质,对所提取的黄酮类物质进行验证,并用紫外分光光度法测定含量。结果测得样品中总黄酮的含量C=1.204 mg/ml,回收率为98.29%,其纯度和产率均较高。结论该方法采用全物理过程,无污染,是提取龙眼壳中黄酮类物质的有效途径。
Objective To study the method for extraction and identification of total flavanone of longan shell. Methods The flavonoids were extracted by ethanol as the solvent from longan shell with ultrasonic wave. Spectrophotometry was used to determine the flavanone of longan shell. Results The content of the total flavanone of longan shell obtained by this method was C = 1. 204 mg/ml and the rate of recovery was 98.29%. Conclusion This text provides the extraction and purification methods to get the outcome and the purity of the flavanone is high. This method is a purely physical process and has no pollution. It is an ideal way to extract the flavanone of longan shell.
