      【摘要】  采用L-8900型氨基酸自動分析儀,測定了紅麻與大花白麻兩種羅布麻葉中氨基酸的種類與含量。結果顯示兩種羅布麻葉中氨基酸的種類均較為豐富,均含有16種氨基酸,兩種羅布麻葉所含人體必需氨基酸總量與藥效氨基酸總量占氨基酸總含量的比例基本一致,紅麻的氨基酸總含量為11.82 g?(100 g) -1, 顯著高于大花白麻的氨基酸總含量6.86 g?(100 g) -1,結果表明紅麻的食用及藥用價值高于大花白麻。

      Abstract The amino acid contents in Apocynum venetum L and Poacynum hendersonii (Hook.f.) Woodson were determined and analyzed by using L-8900 amino acid analyzer. It was found that Apocynum venetum L and Poacynum hendersonii (Hook.f.) Woodson all contain sixteen kinds of amino acids, and the contents of essential amino acids and medicinal amino acids in the total amino acids were similar. The total contents of amino acids was 11.82 g?(100 g) -1 in Apocynum venetum L,which was significantly higher than the total contents of amino acids was 6.86 g?(100 g) -1 in Poacynum hendersonii (Hook.f.) Woodson. The result showed that Apocynum venetum L has the higher edible value and medical value than Poacynum hendersonii (Hook.f.) Woodson.

      羅布麻屬夾竹桃科,直立半灌木,高約1.5-3m,別名野麻、紅麻、茶葉花,吉吉麻,野茶,澤漆麻、羅布歡的爾(維吾爾名)。主要生長于鹽堿荒地、沙漠邊緣、戈壁荒灘及河流周圍。新疆是羅布麻的主要產區,羅布麻有三個品種,紅麻,白麻和大花白麻,其資源可供開發利用者為紅麻和大花白麻。[1] 現代醫學證明羅布麻主要含有:黃酮類化合物、強心苷、氨基酸、多種微量元素等。[2]具有平肝安神,清熱利水的作用,可用于治療肝陽眩暈,心悸失眠,浮腫尿少,高血壓,神經衰弱,腎炎浮腫。[3] 本試驗采用L-8900氨基酸自動分析儀測定紅麻與大花白麻兩種羅布麻葉中氨基酸的含量差異,為新疆羅布麻葉資源的開發利用提供基礎性研究資料。
