摘　　要：目的建立骨痛贴制剂的质量标准。方法采用TLC法鉴别方中黄柏、葛根、丹参、冰片;用HPLC法测定方中君药黄连中的盐酸小檗碱,色谱柱采用Diamonsil C18(150 mm×4.6 mm,5μm),以乙腈-0.1 mol.L-1磷酸二氢钾溶液-0.025 mo.lL-1十二烷基硫酸钠溶液(50:25:25)为流动相,检测波长为345 nm,流速为1 m.lmin-1,柱温为25℃。结果定性鉴别的分离度良好、专属性强、阴性无干扰;盐酸小檗碱的线性范围为0.3636~3.9999μg(r=0.9999),平均回收率为100.89%,RSD=1.42%。结论所建方法操作简单、快速,结果准确、可靠,可作为骨痛贴质量控制的方法。OBJECTIVE To establish the quality standard of Gutong applicator.METHODS Cortex Phellodendri Chinensis,Pueraria lobata(Willd.)Ohwi,Radix Salviae miltorrhizae,Borneolum syntheticum were identified by TLC.The content of berberine hydrochloride was determined by HPLC.The column was Diamonsil C18(150 mm×4.6 mm,5 μm).The mobile phase consisted of acetonitrile-0.1 mol·L-1 monopotassium phosphate-sodium dodecyl sulfate(50:25:25).The detection wavelength was 345 nm.The flow rate was 1 ml·min-1 with column temperatu...
