不同提取溶剂系统对类胡萝卜素总含量的影响

在众多类胡萝卜素的定量分析报道中,相同的样品材料结果却存在较大的差异,作为分析检测的第一步——样品提取过程对于结果中误差的大小起关键作用。本文对不同类型的材料,采用报道的六种不同的提取溶剂系统按相同的步骤进行提取,比较总类胡萝卜素的含量。结果表明,材料的类型对于提取溶剂的选择极其重要,溶剂的选择不当,将造成类胡萝卜素提取得不完全。

In the many reports of carotenoid quantitative analysis, there are large differences among the results from the same materials. Extraction as the first step of carotenoids analysis plays a key rote for the errors from results, This paper compares data of carotenoids content obtained from six different extraction solvent systems which have been reported according to the same extraction procedure. The results shows that extraction solvent is extremely important for carotenoid analysis of different materials and the improper choice of extraction solvents will result in incomplete extraction of carotenoids.
