Abstract Objectlve:To determine the content of protein and free amino acid within the residues of the Uygur medicine. Methods:The protein and amino acid content were determined by spectrophotometry with colored by coomassie brilliant blue G-250 and inhydrin. Results:The linear range of protein determined by CBB G-250 chromogenic assay was 0. 081~0. 202mg,recovery was 102. 06%,RSD was 0. 99%;the linear range of free amino acid by Ninhydrin chromogenic assay was 0. 016-0. 029mg/mL,recovery was 99. 83%,RSD was 1. 82%. Concluslon:CBB G-250 and ninhydrin chromogenic assay is simple,rapid with high sensitivity,low cost,fine reproducible characteristics and so on.

我国药渣根据原料来源,类型主要有中药渣、生物制药药渣、藏药渣、抗生素类药渣等,其中中药渣所占的比例最大。据统计,中药渣在我国的排放量逐渐增加,平均年排放量已达3千万吨[1]。药渣中含有丰富的粗蛋白、碳水化合物、粗纤维、无机物和粗脂肪等[2-5],这些药渣若被丢弃会对环境造成严重的污染,这些药渣的处理将是刻不容缓的问题。本实验测定蛋白质及氨基酸的含量,有效的解决药渣的处理难题,易污染等问题,并为后期如何利用药渣栽培食用菌[6-7]、制成有机肥[8-9]提供理论依据和数据。
