摘要
蝗虫含有丰富的黄酮,不同品种之间和同一品种不同地域之间有很大差异。稻蝗的黄酮含量最高,内蒙黄胫小车蝗的含量最低。采用有机溶剂提取法对内蒙黄胫小车蝗的黄酮提取工艺进行了研究,结果表明,甲醇对内蒙黄胫小车蝗的黄酮具有很好的提取效果,其最佳提取工艺条件为:提取时间24 h,料液比1:30,黄酮的提取量为293.2 mg/100 g。
The content, extracting technology and preparatory isolation of locust flavonoids was studied in this paper. The result showed that there was a great difference among species and latitudes. Methanol had preferable extraction effect for flavonoids and the optimum technological condition was dipping dried locust in methanol with the scale 1：30 of raw material and solvent for 24 h. The extracting content of flavonoids was 293.2 mg/100 g. It has a rosy future in eating.
