6—去氧四环素中乙醇的含量,在我国药典中尚无此项指标。本文建立了用气相色谱法测定6—去氧四环素中乙醇含量的定量方法。采用401有机载体为国定相,氢火焰离子化检测器,以正丙醇为内标进行定量。相对偏差小于2％。本法有简便、快速和准确等优点。
6-deoxy tetracycline in the content of ethanol, there is no such indicator in our pharmacopoeia. This paper established a quantitative method for the determination of ethanol in 6-deoxytetracycline by gas chromatography. Using 401 organic carrier for the national phase, flame ionization detector to n-propanol as internal standard for quantitative. The relative deviation is less than 2%. This law is simple, fast and accurate and so on.
