摘 要:目的:以壳聚糖为基质制备盐酸利多卡因凝胶剂,并建立盐酸利多卡因的含量测定方法。方法:以壳聚糖为基质制备凝胶剂,以HPLC法测定利多卡因的含量;色谱条件为Kromasil C18色谱柱(200 mm×4.6 mm,5μm,);流动相:甲醇-磷酸缓冲液(加磷酸调节p H=8.00)(75∶25),流速为0.8 ml/min,检测波长为254 nm,柱温:室温,进样量20μl。结果:盐酸利多卡因在16.24~121.80μg/ml范围内浓度与峰面积线性关系良好(r=0.999 9,n=7),平均回收率为100.59%,RSD为0.35%。结论:以壳聚糖为基质制备的凝胶剂方法简便,HPLC法测定凝胶剂中的利多卡因方法准确、可靠,可用于对利多卡因凝胶剂进行质量控制、含量控制。Objectives:Preparation of chitosan as the matrix of lidocaine hydrochloride gels,to establish content determination and methodology of the method. Methods: Design the prescription,according to the prescription preparation gels. To establish HPLC method for determining the content of lidocaine,the chromatographic conditions is Kromasil C18 chromatographic column(200mm × 4. 6 mm,5 μm); mobile phase: methanol- phosphate buffer(75∶ 25); add phosphoric acid to adjust p H 8. 0,flow rate of 0. 8 ml / min,λmax= 254 nm;column temperature: room temperat ure,injection amount 20 μl. Results:The calibration curves of lidocaine were linear in the ran ges of 16. 24 ~ 121. 8 μg / ml( r = 0. 999 9,n = 7). The recoveries were 100. 59%,and RSD were0. 35%( n = 3). Conclusions: The methods of HPLC is specific,effective,sensitive and accurate. It can be used to lidocaine hydrochloride gel agent for quality control,content control.
