| Abstract: |
| Detectionation of organic acids in Maojian green tea by HPLC was studied. A reversed-phase C18 column was used with the mobile phase of 0.05 mol/L KH2PO4 （pH=2.7）at 0.6 mL/min and detection wavelength at 210 nm and column temperature of 30℃，it can be seperated well for the seven organic acids in MaoJian green tea. The organic acids had good linear in the linear range with
recoveries between 95.6%~102.5%. The method was simple，rapid and with high accuracy which was suitable for determination of organic acids in green tea. |
