OBJECTIVE To establish an HPLC method for the determination of aciclovir in eye gel. METHODS Analytical column was Hypersil C 18(5 μm,250mm× 4.6 mm),The mobile phase was composed of methanol-water(8∶92) with 0.1% glacial acetic acid. The detection wavelength was 252 nm and the peak area was calculated.RESULTS The Calibration curve was linear within the concentration range of 12~32 mg·L -1.The average recovery of aciclovir was 99.72%,RSD was 0.40%.CONCLUSIONS The method is simple,rapid and acc...
