摘要
本文基于在乙醇介质中有抗坏血酸存在时能够使VE避免氧化;60％硫酸能够抑制VA对测定VE的干扰这样两个实验结果,提出了一个简便、快速测定作物种子VE总量的荧光法。样品可不经充氮皂化和柱分离即能得到较满意的分析结果。小麦、黄玉米、谷子、黄豆的回收率分別为102、96、103、104％;其相对标准偏差分别为2.6、0.5、2.2、1.5％。方法适用于批量种子样品的例行分析。
A simple, rapid and accurate spectrofluorometric method has been developed for determination of vitamin E in crop seeds. Several experiment conditions were discussed in detail. Linear analytical curve was obtained in concentration of 0-55ug of vitamin E in 10 ml solution. The precisions were 0.5-2.9% relative SD. The recoveries were 86-104%.
