| Abstract: | Objective To establish an HPLC method for the determination of Nateglinide Capsule.Methods Phenomenex ODS-3 C18（150 mm× 4.6 mm,5 μm）Column was adopted,the mobile phase consisted of acetonitrile-methanol-0.05 mol·L-1 dibasic potassium phosphate（adjusted pH6.0 with phosphoric acid）（35∶ 10∶ 55）,the flow rate was 1.0 mL·min-1,the detection wavelength was 210 nm,the column temperature was 35 ℃.Results A good linear relationship was observed in the concentration range of 8～80 μg·mL-1（r=0.999 3）,the average recovery was 99.9%,RSD=0.36%（n=9）.Conclusion The method was simple,accurate and sensitive,and was suitable for the quality control of Nateglinide Capsule. |
