摘要
目的:建立同时测定艾滋病口腔含漱液中梓醇、哈巴苷和哈巴俄苷含量的方法。方法:采用双波长超高效液相色谱法,色谱柱为Eclipse Plus C18,流动相为乙腈-0.05%磷酸溶液(梯度洗脱),流速为0.2 ml/min,波长切换,0~8 min在210 nm波长测定梓醇和哈巴苷的含量,8~15 min在280 nm波长测定哈巴俄苷的含量,柱温为30℃,进样量为2μl。结果:梓醇、哈巴苷、哈巴俄苷进样量分别在0.018 5~0.129 2、0.014 0~0.098 3、0.015 7~0.110 0μg范围内与各自峰面积呈良好的线性关系(r=0.999 6、0.999 7、0.999 7);精密度、稳定性、重复性试验的RSD≤0.77%;平均加样回收率分别为99.44%、99.90%、100.20%,RSD分别为0.75%、0.82%、0.73%(n=6)。结论:该方法操作简便、重复性好,可以更有效地控制艾滋病口腔含漱液的质量。
OBJECTIVE: To establish a method for simultaneous determination of the content of catalpol, harpagide and hapagoside in AIDS oral gargle. METHODS: Dual-wavelength UPLC was performed on the column of Eclipse Plus C18 with mobile phase of acetonitrile-0.05% phosphoric acid (gradient elution) at the flow rate of 0.2 ml/min. Wavelength was switching, it was set at 210 nm to determine the contents of catalpol and harpagide in the first 8 min and then changed to 280 nm to determine the content of hapagoside in 8-15 min. The column temperature was 30 ℃ ,and injection volume was 2 μl. RESULTS: The linear range was 0.018 5-0.129 2 μg (r=0.999 6) for catalpol, 0.014 0-0.098 3 μg (r=0.999 7) for harpagide and 0.015 7-0.110 0 μg(r= 0.999 7) for hapagoside; RSDs of precision, stability and reproducibility tests were no more than 0.77%; average recoveries were respectively 99.44% (RSD=0.75%, n=6), 99.90% (RSD=0.82%, n=6) and 100.20% (RSD=0.73%, n=6). CONCLUSIONS : The method is simple can reproducible, and can be used for effectively quality control.
