목적:건립염산거양신상선소주사액중의지산이납함량적반상액상색보측정방법。방법:채용Kromasil C8색보주(4.6 mm×250 mm,5μm),이갑순-10%사정기경양화안용액-98%갑산-수(125:12:0.5:875)위류동상,류속1.5 ml/min,주온40℃,검측파장254 nm,진양체적20μl。결과:의지산이납농도재5.06~50.55μg/ml범위내여봉면적정량호적선성관계(r=0.999),평균회수솔위101.0%。결론:해방법쾌속、간편、전속성강、중복성호,결과준학가고,괄용우염산거양신상선소주사액중의지산이납적함량측정。
Objective: To establish a RP-HPLC method for the quantitative analysis of disodium edetate in phenylephrine hydrochloride injection. Methods:RP-HPLC was performed using a Kromasil C8 column (4.6 mm×250 mm, 5 μm) with the mobile phase of methanol-10% tetrebutyl ammonium hydroxide-98% formic acid- water( 125:12:0.5:875) and UV detection wavelength of 254 nm at the lfow rate of 1.5 ml·min-1 and column temperature of 40℃. Results:The standard curve was linear over the range of 5.06~50.55 μg/ml (r=0.999) and the average recovery was 101.0%for disodium edetate. Conclusion:This method is simple, accurate, sensitive and good reproducible, and can be applied in the determination of disodium edetate in phenylephrine hydrochloride injection.
