鳄嘴花叶氨基酸和微量元素分析及其化学成分研究

Analysis of Amino Acids,Trace Elements and Chemical Constituents from the Leaves of Clinacanthus nutans

目的分析鳄嘴花叶中的氨基酸、微量元素及主要化学成分。方法采用HPLC法和等离子体发射光谱法测定了鳄嘴花叶中氨基酸和微量元素的成分和含量,采用柱色谱法对鳄嘴花叶中的主要化学成分进行研究。结果从鳄嘴花叶中分析测定出了17种氨基酸和11种微量元素,叶中总氨基酸含量达11.54%。分离鉴定出4种主要化学成分,羽扇豆醇(1)、异牡荆苷(2)、β-胡萝卜苷(3)、肥皂草苷(4)。结论鳄嘴花叶富含大量的人体必需氨基酸、微量元素及活性天然产物,具有较高的营养价值和药用价值。

Objective To analyze amino acids, trace elements and chemical constituents from the leaves of Clinacanthus nutans. Methods The amino acids and trace elements were detected by HPLC and ICP-OES, respectively. Chemical constituents were identified by the combination of column chromatography and spectral analysis. Results The leaves contained seventeen varieties of amino acids, eleven trace elements, and four primary chemical components. Conclusion The leaves are rich in amino acids, trace elements and bioactive chemical constituents, suggesting that Clinacanthus nutans is of high nutritional value.
