| Abstract: | OBJECTIVE： To establish the method for the content determination of main component of Metformin hydrochloride sustained- release tablets. METHODS：HPLC was conducted on a Hypersil ODS2 with mobile phase consisted of 0.05% sodium heptanesulfonate solution （pH adjusted to 4.0）-acetonitrile （84 ∶ 16） at a flow rate of 1.0 mL·min-1. The UV detection wavelength was set at 233 nm. The injection volume was 20 μL and the column temperature was 30℃. RESULTS： The linear range of metformin hydrochloride was 0.11～10.70 μg·mL-1 （r=0.999 7） with an average recovery of 98.17%, 99.69%, 100.19%（RSD=0.60%）. CONCLUSION： The method is simple and accurate for the content determination of Metformin hydrochloride sustained-release tablets. |
