刺葡萄汁与其它几种葡萄汁及葡萄酒的原花青素含量对比

Contrast of the procyanidins content in Vitis davidii Foex and some other grape juices and wines

采用铁盐催化比色法,对刺葡萄汁、巨峰葡萄汁以及几种商品葡萄汁和2种葡萄酒中的原花青素含量进行了对比测定。结果表明:刺葡萄汁中的原花青素含量为3147μg/mL,巨峰葡萄汁为1187μg/mL,Welch’s紫葡萄汁2476μg/mL,蒙娜丽莎干红葡萄酒2854μg/mL,长城干红葡萄酒2757μg/mL,可见刺葡萄汁中原花青素含量显著高于其它葡萄汁和葡萄酒中的含量。

The procyanidins content in grape juice of Vitis davidii Foex, Kyoho grape juice, some other grape juices and two wines were determined with ferric ions as catalysis agent. The results showed that procyanidins contents of Vitis davidii Foex grape juice, Kyoho grape juice, Welch＇ s purple grape juice, Madamlisa dry grape wine, and Great wall dry wine were 3147μg/mL, 1187μg/mL, 2476μg/ mL, 2854μg/mL, and 2854μg/mL, respectively. The procyanidins content in grape juice of Vitis davidii Foex was the highest.
