摘　　要：采用国标方法测定了菜用黄麻(甜黄麻)的灰分、粗蛋白和可溶性糖含量;采用原子吸收分光光度法测定K、Ca、Mg、Na、Mn、Fe、Zn和Cu含量;采用日本日立L-8800全自动氨基酸分析仪测定氨基酸含量。结果表明:甜黄麻所含粗蛋白、矿质元素和氨基酸十分丰富,其中K含量6740mg·kg-1、Ca含量4450mg·kg-1、Na含量30.2mg·kg-1。The content of crude ashes, crude proteins, soluble sugars and 8 mineral elements including K, Ca, Mg, Na, Mn, Fe, Zn and Cu and 17 kinds of amino acids were determined with vegetable jute（Corchorus olitorius L.）‘Tianhuangma’as material by traditional method AAS（atomic absorption spectrophotometry）and Japan＇s Hitachi L-8800 automatic amino acid analyzer, respectively. The results indicate that there are extremely rich crude proteins, mineral elements and amino acids in‘Tianhuangma’. Its K content is 6 740 mg·kg^-1, Ca content is 4 450 mg·kg^-1, Na content is 30.2 mg·kg^-1.
