摘　　要：用高效液相色谱对9种鹤、鹳羽毛角蛋白的氨基酸组成与含量进行检测分析。结果表明,鹤类与鹳类的羽毛角蛋白均有各自较为相近的氨基酸构成比例,氨基酸组成的种类相同,仅在相对含量上有差异。与其他动物比较发现,不同科属的动物羽或毛角蛋白的氨基酸构成含量不同,具有特征性;相同科属的动物羽或毛角蛋白的氨基酸构成含量具有不同程度的相同或相近性。本文本着建立对野生动物无伤害性研究方法的宗旨,通过对鹤、鹳羽毛角蛋白的氨基酸组成分析探索该方法在野生动物分类、识别与鉴定上的可行性。The amino acids composition of keratin in the feather of cranes and storks was analyzed by using high performance liquid chromatography （ HPLC）. The results showed that there were a similar proportion and the same varieties of amino acids in the feather of cranes and storks, with only some differences in the relative quantities. Compared with other animals, it was found that there was difference in proportion of the amino acids of the hair or feather keratins from different families or genera, with their own characteristics. The characteristics displayed more similar in the same families or genera. This paper intended to establish harmless measuring method for the wild-lives identification. The feasibility of the method in the wildlife classification, recognition and identification was tested through this experiment.
