为了有效地从富含蛋白的牧草中提取叶蛋白，对苜蓿采用６种不同的方法进行提取试验，从中选出了最佳提取方法。并对蛋白、纤维、糖浆产品中有关元素、各种氨基酸等进行了详细分析研究。结果表明，蛋白产品中其蛋白质含量在５０％以上，纤维产品中蛋白质含量在２０％以上。值得注意的是蛋白产品中有关元素含量很高，各种氨基酸含量不但高，而且比例协调。因此，从富含蛋白的牧草中提取叶蛋白是解决我国蛋白质营养匮乏的重要途径 In order to effectively extract leaf protein from protein-rich pasture, alfalfa was extracted by six different methods and the best extraction method was selected. And protein, fiber, syrup products related elements, a variety of amino acids were analyzed in detail. The results showed that the protein content of protein products in more than 50%, fiber products in more than 20% protein content. It is noteworthy that the protein content of the product is high, a variety of amino acids not only high, but the proportion of coordination. Therefore, the extraction of leaf protein from protein-rich pasture is an important way to solve the problem of protein nutrition deficiency in our country
