本文报道用气液层析法测定含有大量糖的多种维生素制剂中的肌醇。将多种维生素制剂样品使三甲基硅烷化后在2%OV-101柱上分离。定量分析系以甲基花生酯作内标,用峰高比的方法计算。作者用本法测定了十三种含有200～1000倍糖的肌醇混合物,回收率良好。实验:用岛津GC-6AM型气相层析仪,以火焰离子检测器检测。层析柱为2米×3毫米(内径)玻璃柱;以涂有2%OV-101的Shimalite W(80～100目)填充,柱温自180°起以5°/分升至30°,载气N_2,流速为17毫米/份。取0.2毫升(含肌醇约0.1毫克)试样,加入
This article reports the measurement of myo-inositol in a variety of vitamin preparations containing a large amount of sugar by gas-liquid chromatography. Samples of multiple vitamin preparations were trimethylsilylated and separated on a 2% OV-101 column. Quantitative analysis of methyl peanut ester as an internal standard, calculated by the peak height ratio method. The authors used this method to determine thirteen inositol blends containing 200-1000 saccharides, with good recoveries. Experiment: Shimadzu GC-6AM gas chromatography, flame ionization detector test. The column was a glass column of 2 m × 3 mm (inner diameter) packed with Shimalite W (80-100 mesh) coated with 2% OV-101. The column temperature was increased from 180 ° to 5 ° / Carrier gas N_2, flow rate of 17 mm / parts. Take 0.2 ml (containing inositol about 0.1 mg) sample was added
