摘要
选取硬质小麦、软质小麦、大麦、小米、玉米、黑麦和高粱共48个不同品种谷物,用偏磷酸溶液进行抽提,然后用高效液相色谱方法定量分析各种形式维生素B6的含量,比较不同种类谷物中维生素B6的存在形式及其含量的差异。结果表明:各种谷物中维生素B6的主要形式是吡哆醇和吡哆葡萄糖甙,几乎没有其他形式存在。不同谷物中吡哆醇和吡哆醇葡萄糖甙的含量差别较大,两种形式的比例也不相同。还根据两种形式维生素B6在人体内的分子生物利用率对各种谷物维生素B6的有效含量进行计算和评估。
Seven kinds of cereals were analysed for different B 6 vitamers using metaphosphoric acid extraction and quantitation with high performance liquid chromatography.The results revealed that pyridoxine(PN)and pyridoxine glucoside(PNG) were the predominant vitameric forms of vitamin B 6 cereals.Other vitameric forms of B 6 were not detected.The amounts of available vitamin B 6 in different cereals were estimated and compared according to the bioavailability of PNG in human.
