摘要: 为快速、方便地测定大蒜中的蒜氨酸,以鲜蒜为原料,经去皮、加热、制汁、与4-巯基吡啶(4-MP)反应、324纳米测定其吸光度等处理,测知鲜蒜中蒜氨酸的含量为0.74%~0.92%,变异系数2.4%~8.8%,结果表明,4-MP比色法测定大蒜中的蒜氨酸,简单、快速、方便,可用于鲜蒜与保藏大蒜中蒜氨酸含量的测定。

Abstract: In order to assay the alliin in garlic (Allium sativum L.),the content of alliin was assayed by the reaction of 4- mercaptopyridine with thiosulfinates formed from the alliin.The optical difference at 324 nm between the samples with and without alliinase was proportional to the contents of alliin. The alliin was amounted to 0.74%~0.92% in the three types of garlic. The method is simple, fast and easy to be used in the plant of garlic processing.

Key words:  , garlic(Allium sativum L.); alliin; 4-mercaptopyridine;
