目的:建立儿童用药头孢地尼颗粒中二硫化二苯并噻唑的检测方法。方法:采用高效液相色谱法,以甲醇∶水=80∶20为流动相,柱温35℃,检测波长 275 nm。结果:在检测范围内,二硫化二苯并噻唑有良好的线性关系(r=0。9994),精密度良好(RSD为 2。7%,n=6),平均回收率为99。4%(RSD为 2。0%,n=9),在 25℃24 小时内溶液稳定性良好。结论:高效液相色谱法作为检测方法,灵敏度高,专属性强,可用于头孢地尼颗粒中二硫化二苯并噻唑的测定。
Detection of Dibenzothiazole Disulfide in Cefdinir Granules
Objective:To establish an analysis method for the determination of dibenzothiazole disulfide in cefdinirgraunles.Methods:HPLC method was used with methol:water=80:20 as mobile phase,column temperature of 35℃,detection wavelength of 275 nm.Results:Within the detection range,dibenzothiazole disulfide had a good linear relationship(r=0.9994),good precision(RSD of 2.7%,n=6),average recovery of 99.4%(RSD of 2.0%,n=9),and good solution stability at 25℃for 24 hours.Conclusion:As a detection method,HPLC has high sensitivity and strong specificity,and can be used for the determination of dibenzothiazole disulfide in cefdinir granules.
