采用核磁共振仪分析油菜籽含油量，与索氏抽提法相比，样品用量少，测量速度快，且不损伤样品。通过 两种方法的对比测定，相关系数 r=0.9818,并给出标准曲线 y=-0.082＋ 10.710x,进一步对 NMR方法的测量准确 性、精密度和重现性进行验证，完善了 NMR测定基本操作方法，提高育种分析效率。 The NMR analysis of rapeseed oil content, compared with the Soxhlet extraction method, the sample dosage is less, the measurement speed, and does not damage the sample. By comparison of the two methods, the correlation coefficient r = 0.9818 and the standard curve y = -0.082 + 10.710x, the accuracy, precision and reproducibility of the NMR method were further verified, and the basic principles of NMR determination Operating methods to improve the efficiency of breeding analysis.
