盐藻浸膏中主要活性成分研究

Study on Main Active Components in the Extract of Dunaliella Salina

目的测定盐藻浸膏中类胡萝卜素、氨基酸、脂肪酸、维生素及微量元素等活性成分,为进一步利用盐藻资源提供依据。方法类胡萝卜素、维生素根据具体成分性质选用比色法和高效液相色谱法(HPLC);氨基酸的分析由日立835-50型氨基酸分析仪完成;不饱和脂肪酸的测定采用气相色谱法;采用原子吸收分光光度法测定钾、钠、钙、镁、铜、锌、磷、铁、锰元素;采用荧光分光光度法测定硒元素。结果盐藻浸膏中含有丰富的类胡萝卜素、氨基酸、脂肪酸、维生素及微量元素等活性成分。结论盐藻浸膏可以作为一种天然保健食品原料,具有开发价值和市场前景。

Objective To provide a basis for further exploration of DunalieUa Salina by determining the main active components in the extract of DunalieUa salina. Methods The carotenoids and vitamins were determined by HPLC or colofimetric method, amino acids were analyzed by amino acid analyze. Unsaturated fatty acid was determined by GC. Atomic absorption spectrophotometry was used to detect K, Na ,Ca, Mg, Cu, Zn, P, Fe, Mn and SPF was used to detect Se. Results There were affluent carotenoids, vitamins, amino acids, unsaturated fatty acid and trace elements in the extract of Dunaliella salina.Conclusion The extract of Dunaliella salina could be used as natural raw material to develop the supplement food.
