摘要

建立了气相色谱/燃烧/同位素比质谱仪(GC/C/IRMS)测定富13C草酸盐中13C丰度的分析方法。GC/C/IRMS测定的草酸13C原子%值与全自动氮碳分析仪-质谱联用仪(ANCA-MS)测定值基本相等，相关性高(r2=0.9999)，重现性好(CV=0.224%)。该方法可用于菠菜草酸代谢的研究。

ガスクロマトグラフ-燃焼-同位体比質量分析計によるホウレンソウ中のシュウ酸の炭素同位体組成分析法

An analytical method to measure 13C abundance in 13C enriched oxalate using gas chromatograph/combustion/isotope ratio mass spectormeter (GC/C/IRMS) was established. The 13C atom% values of oxalate measured by GC/C/IRMS were nearly equal to those measured by automated nitrogen and carbon analyzer-mass spectrometer (ANCA-MS) giving a high degree of correlation (r2=0.9999) and good reproducibility (CV=0.224%). This method will be applicable in the study of oxalate metabolism in spinach.
