摘　　要：[目的]分析成都麻羊肉氨基酸和矿物质含量,为其种质特性研究提供参考。[方法]采用2×2×3 3因子试验方法,对成都麻羊不同年龄(周岁和成年)、不同性别(羯羊和母羊)和不同解剖部位(背最长肌、股二头肌和腰大肌)的肉氨基酸和矿物质含量进行分析。[结果]成都麻羊肉平均氨基酸总量、成人必需氨基酸和婴儿必需氨基酸分别为(21.41±1.93)(、9.27±0.89)和(10.74±1.02)mg/100 mg。所测17种氨基酸在不同年龄、不同性别和不同解剖部位羊肉间存在差异。除苏氨酸外,其余所测氨基酸以及鲜味氨基酸和氨基酸总量周岁羊肉分别显著(P<0.05)或极显著(P<0.01)大于成年羊肉;氨基酸总量、成人必需氨基酸母羊肉均显著大于羯羊肉(P<0.05),背最长肌显著大于股二肌和腰大肌(P<0.05)。成都麻羊肉7种矿物质含量,除钙外,成年羊肉均高于周岁羊肉,羯羊肉高于母羊肉,股二肌显著(P<0.05)或极显著(P<0.01)高于背最长肌和腰大肌。[结论]成都麻羊肉具有营养丰富、肉质优良和肉味鲜美的宝贵种质特性。[Objective] The research aimed to study the amino acids and mineral elements contents of Chengdu Ma goat. [ Method] A completely ranomized design involving a 2 × 2 × 3 factorial arrangement at different ages （adult, one-year old）, gender（male, female） and anatomical regions （longissmus dorsi muscle,biceps femofis muscle,psoas major muscle） was designed. And amino acids and mineral elements contents were analyzed. [Result] The results showed that the contents of mean total amino acid,adult essential amino acid,and baby essential amino acid were （21.41 ± 1.93）, （9.27 ± 0.89） and （10.74± 1.02）mg/100 mg respectively.The contents of examined 17 amino acids were affected by age,gender,and anatomical regions.Except threonine, the contents of all examined amino acids tasty amino acids contents （ P 〈 0.05） ,and total amino acid contents（ P 〈 0.01 ） were affected by age greatly ,and the adult Ma goat was larger.The total amino acid content and adult essential amino acid content were affected by gender （P〈0.05） and anatomical regions （P〈O.05）.Thereinto, the female goat was larger than the male goat （P 〈 0.05）,and the longissimus dorsi muscle was larger than the biceps femoris muscle and psoas major muscle （P 〈 0.05）. Except calcium, the examined 7 mineral elements were affcted by age, genderand anatomical regions. The mineral elements contents of adult,male,and biceps femofis muscle were larger than one year old（ P 〈0.05） ,female（ P 〈0.05）,and the other muscles（P 〈 0.05 or P 〈 0.01 ） respectively. [Conclusion] The results indicated that the Chengdu Ma goat was rich in nutritional ingredient.
