【摘要】 <正> 菜籽粕是重要的饲用蛋白资源。由于粕中含有水溶性芥子苷,在动物体内会酶解成油溶性毒物,如异硫氰酸酯、腈类等,使粕的应用受到限制。各地芥子苷种类不一,酶解产物也不完全相同。因此研究芥子苷酶解产物具有重要意义。关于国外十字花科植物中芥子苷酶解产物的色/质联用分析已有报道。但未见有关中国菜籽粕中芥子苷酶解产物的报道。本文探讨了芥子酶的制备及酶解芥子苷的技术,并用色/质联用技术对酶解产物进行定性分析。更多还原

【Abstract】 Myrosinase was extracted from white mustard seeds and was used for enzyme-hydrolysis of glucosinolates. GC-MS was used for identifying the major products of enzyme-hydrolysis.The separation was accomplished on SP-1000 glas; capillary column with two-step temperature programm. The constitutional formulas of eleven components were determined.更多还原
