摘　　要：旨在为西伯利亚白刺不同部位的17种氨基酸测定提供理论基础和科学依据。从研究区采集白刺的果实、种子、叶等不同部位为分析样品材料。通过采用盐酸水解法对样品中17种氨基酸进行化学测定分析,检测白刺果、种、叶中氨基酸的种类和含量。结果表明：白刺干果中7种人体必需氨基酸含量为0.187~0.781 g/100 g,其中亮氨酸含量最高为0.781 g/100 g。2种半必需氨基酸（精氨酸,组氨酸）和7种非必需氨基酸的含量均为0.127~1.312 g/100 g。种子中7种人体必需氨基酸含量为0.065~0.795 g/100 g,其中亮氨酸含量最高为0.795 g/100 g。种子中2种半必需氨基酸和7种非必需氨基酸的含量为0.127~2.136 g/100 g,其中谷氨酸含量最高为2.136 g/100 g。在不同时期的干叶子中已检测的7种人体必需氨基酸含量由高到低依次为7月份4.392 g/100 g〉6月份3.885 g/100 g〉9月份3.307 g/100 g。2种半必需氨基酸和7种非必需氨基酸的含量由高到低依次为7月份8.783 g/100 g〉6月份7.456 g/100 g〉9月份6.452 g/100 g。本研究结果表明西伯利亚白刺果、种、叶等部位均有较高含量的17种氨基酸。The objective was to provide theoretical and scientific basis for determining 17 kinds of amino acidsin different parts of Nitraria sibirica. The fruits, seeds, leaves and other parts of Nitraria sibirica were collectedin research area as the materials. The chemical determination of 17 kinds of amino acids in the samples wascarried out by using hydrochloric acid hydrolysis method, the kind and contents of amino acids from fruits,seeds and leaves of the Nitraria sibirica were detected. The results showed that, the contents of 7 kinds ofamino acids in dry fruits which were essential to human body were 0.187-0.781 g/100 g, and leucine with thehighest content was up to 0.781 g/100 g. The contents of 2 half essential amino acids and 7 non-essentialamino acids were 0.127-1.312 g/100 g. The content of 7 amino acids which were essential for human body inseeds was 0.065-0.795 g/100 g, and leucine with the highest content was up to 0.795 g/100 g. The contents of2 half essential amino acids and 7 non-essential amino acids in seeds were 0.127-2.136 g/100 g, and glutamicacid with the highest content was up to 2.136 g/100 g. The contents of 7 amino acids essential to human body ofdry leaves in different periods, from high to low was July 4.392 g/100 g〉June 3.885 g/100 g〉September3.307 g/100 g. At the same time, the contents of 2 half essential amino acids and 7 non-essential amino acidsfrom high to low was July 8.783 g/100 g〉June 7.456 g/100 g〉September 6.452 g/100 g. It is concluded that fruits, seeds and leaves of Nitraria sbirica all have relatively high contents of the 17 kinds of amino acids.
