摘要
采用氨基酸分析仪测定了杜梨叶片中18种氨基酸,原子吸收分光光度法测定了12种矿质元素。分析结果表明,杜梨叶片氨基酸含量丰富,含有人体必需的8种必需氨基酸,氨基酸总量达到了11.68%;微量元素铜、锰、铁等的含量丰富,分别达到了7.847μg/g、33.97μg/g、375.17μg/g。
The amino acid analyzer was used to determine 18 kinds of amino acids in leaf of Pyrus Betulaefolia Bge,and 12 kinds of mineral elements were determined with atomic absorption spectrophotometry. The experiment indicated that amino acids were abundantly in the leaf of Pyrus Betulaefolia Bge. , containing 8 kinds of essential amino acids, and the total of amino acids took up 11.68%. The contents of trace elements were respectively as follow, Cu （μg/g） 7. 847, Mn33.97, Fe375.17.
