Abstract: 目的 建立同时测定妥布霉素滴眼液中5种抑菌剂(羟苯乙酯、硫柳汞、羟苯丙酯、苯扎溴铵和苯扎氯铵)的高效液相色谱(HPLC)方法 .方法采用Agilent Zorbax SB-C18(4.6 mm×150 mm,5μm)色谱柱,流动相A为1%三乙胺(磷酸调节pH值至3.5±0.05);流动相B为甲醇,梯度洗脱,流速为1.0 mL·min-1,柱温35℃,检测波长为214 nm.结果 羟苯乙酯、硫柳汞、羟苯丙酯、苯扎溴铵/苯扎氯铵各峰均分离良好;羟苯乙酯在0.77~192.5μg·mL-1(r=0.9995),硫柳汞在2.16~541.0μg·mL-1(r=0.9997),羟苯丙酯在0.84~209.8μg·mL-1(r=1.0000),苯扎溴铵在4.36~1090μg·mL-1(r=0.9992),苯扎氯铵(n-C12H25)在3.22~805.0μg·mL-1(r=0.9998)及苯扎氯铵(n-C14H29)在1.66~413.9μg·mL-1(r=1.0000)范围内线性关系均良好.结论 该方法准确、灵敏、简便,可用于妥布霉素滴眼液中羟苯乙酯、硫柳汞、羟丙丙酯、苯扎溴铵及苯扎氯铵5种抑菌剂的检查.
