【Abstract】 Objective To develop a method for determine the contents of chloramphenicol and ephedrine hydrochloride in nasal drops. Methods While the determination was carried out, the dual wavelength spectrophotomertic method was used for eliminating mutual interference. Results The method was linear and reproducible The average rate of recovery was 100.4%,RSD=0.5%(.n.=6),for chloramphenicol and 99.7%,RSD=1.3%(.n.=6),for ephedrine hydrochloride. Conclusion The method was simple,rapid and accurate.更多还原
