摘　　要：对繁缕叶蛋白的浓缩及蛋白质氨基酸组成进行研究与分析,结果表明:繁缕蛋白质含量较高,达到15.39%,在浓缩叶蛋白中的含量达到52.03%。对繁缕叶蛋白氨基酸组成分析表明,各种繁缕叶蛋白的氨基酸的平衡性较好,其必需氨基酸含量、必需氨基酸与非必需氨基酸比值、必需氨基酸评价分数均在FAO/WHO推荐值范围内。This experiment was undertaken to concentrate LPC from Stellaria meida and analyze the amino acid composition of the LPC.The results showed that protein content of dried herbs powder on dry basis was 15.39 %,while that of the LPC was 52.03 %.The analysis of the amino acid composition of LPC from Stellaria meida showed that the balance of amino acid was very good.The essential amino acid content,the ratio of essential amino acid content to non-essential amino acid,and the evaluation of essential amino acid of LPC were accord with those recommended by FAO/WHO.
