目的探索准确而简便地测定α-溴代肉桂醛的含量。方法利用气相色谱法,用玻璃柱以2%OV-17为固定液。结果在7·89~79·8ug/ml的浓度范围具有良好的线性关系,r=0·99998,平均回收率为:①94·93%(n=3),RSD=0·53%,39·1PPm,②95·19%(n=3)RSD=95·19%。66·6PPm。结论本法适用于成品检验及杂质检查。
Objective To explore the determination of α-bromocinnamaldehyde content accurately and easily. Methods Gas chromatography was used with 2% OV-17 glass column as stationary phase. The results showed that there was a good linear relationship between the concentration range of 7 · 89-79 · 8ug / ml, r = 0.99998, the average recoveries were: 94.93% (n = 3), RSD = 0.53% 1PPm, ② 95.19% (n = 3) RSD = 95.19%. 66 · 6PPm. Conclusion This method is suitable for finished product inspection and inspection of impurities.
