【Abstract】 OBJECTIVE To develop an HPLC method for determination of ambroxol hydrochloride.METHODS A Diamonsil(tm) C 18 column(5 μm,250 mm× 4.6 mm)was selected and the mobile phase consisted of acetonitrile-water-ammonia solution-phosphate (30∶70∶ 0.10∶ 0.08,pH= 3.0) at a flow rate of 0.6 mL·min -1. The detection wavelength was 244 nm.RESULTS The standard curve was linear in the rang of 5.92~ 53.3 mg·L -1 (r= 0.9999,n=6). The average recovery and relative standard deviation (RSD) were 100.6% and 0.9%, resp... 更多还原 【关键词】 盐酸氨溴索; 片剂; 高效液相色谱法; 【Key words】 ambroxol hydrochloride; tablets; HPLC;
