【Abstract】 AIM:To establish the method for determining five ingredients in Compound Bendazol and Hydrochlorothiazide Capsules by RP-HPLC METHOD:The separation was performed on a Hypersil ODS2 column(200 mm×4 0 mm,5 μm) Mobile phase composed of methanol-0 14% heptanesulfonic acid sodium salt solution containing 1% acetic acid and 0 1% triethylamine(1∶1) was degassed ultrasonically before use Each component of the mobile phase was filtered through a 0 45 μm membrane The separation was performed at 35 ℃ and the flow-rate was 1 0 ml/min Injection volume was 20 μl All peaks were monitored at UV 258 nm RESULT:The detection limits of hydrochlorothiazide,bendazol,chloroquine phosphate,chlordiazeposide and promethazine hydrochloride were 0 4,0 5,0 3,0 1,0 2 ng respectively The linear ranges were 1 00～98 80,0 96～96 00,1 06～106 40,0 86～85 60,0 84～83 60 μg/ml respectively The average recovery of all compounds was over 98 65 % RSD was less than 0 57% CONCLUSION:The method was simple,rapid,sensitive and reproducible更多还原
