一般說明

全-反式-虾青素属于类胡萝卜素。全反式虾青素是酮式类胡萝卜素,常见于海洋和水生动物,包括磷虾、野生鲑鱼、虹鳟鱼、微藻、龙虾壳、虾 海产品等。 在生物学上将其称为维生素A 前体,具有强大的抗氧化性能,抗氧化能力比维生素E和 β-胡萝卜素大得多。 它在食品行业和医药行业的作用也十分明确。

應用

反式虾青素可作为分析参考标准品,用于:
  • 使用高效液相色谱(HPLC)结合质谱 和荧光检测(HPLC-FLD),定量微藻(绿藻)和雨生红球藻( Haematococcus pluvialis )中的分析物。
  • 使用高效液相色谱(HPLC)和光电二极管阵列检测(PDA)定量哈氏仿对虾(Parapenaeopsis hardwickii )中的分析物。

有关合适的仪器技术的更多信息,请参阅产品′的分析证书。想要获得更多支持,请联系技术服务部。

生化/生理作用

虾青素是在海藻、红酵母和许多植物和动物来源中发现的强效类胡萝卜素抗氧化剂。动物试验表明,它可降低血糖并改善糖尿病代谢综合征的若干指标。可改善高血型模型的血流和血管张力。体外研究表明,它上调间隙联接蛋白 43,可用于化学防癌。
