Lophira中无机元素及氨基酸含量测定

Study on the contents of amino acids and inorganic elements in Lophira

目的 :测定天然植物Lophira中无机元素和氨基酸的含量。方法 :用等离子体原子光谱 ,测定Lophira酸溶液中几种重要无机元素含量 ;用氨基酸自动分析仪测定氨基酸的含量。结果与结论 :天然植物Lophira中具有较高的锌、锶和锰 ;含 18种氨基酸 ,7种为必需氨基酸 ,氨基酸总含量为 2 0 17mg g。

Aim:To determine the contents of some inorganic elements and amino acid in a natural plant——Lophira. Methods: The contents of inorganic elements were determined by ICP and amino acids, by amino analyzer, respectively. Results and conclusion: The contents such as manganese, strontia and zino in this natural plant were high. Eighteen amino acids including seven human essential amino acids were detected. The high contents of some inorganic elements and human essential elements amino acids in Lophira perhaps could explain its folk diagnostic applications to a certain degree.
