摘要
用反相高效液相色谱法测定了大豆胚芽中的α-VE含量,比较了两种不同前处理方法对样品中α-VE含量的影响.结果表明,大豆胚芽中α-VE含量为36.60～46.10mg/100g样品;样品预处理时,超声离心法比皂化离心法处理,测得样品中α-VE含量高出8.29%～15.39%;样品预处理过程中加入抗坏血酸比不加抗坏血酸,测得α-VE含量要高出2.21%～9.16%.
The content of α-VE in soybean germ determined by RF-HPLC the effect of two different pretreatment methods on the content of α-VE in sample was studied. The results showed that the content of α-VE in soybean germ was 36.60-46.10mg/100g germ. Sample was prepared through ultrasonic wave enhancing extraction, the content of α-VE was 8.29%-15.39% higher than that through saponification extraction. The effect of L-Aseorbic acid on the experimental results of α-VE was also obvious.
