ABSTRACT
OBJECTIVE:
To develop a method for the determination of gallic acid in tea pigment injection.METHODS:
RP HLPC method was adopted in which the separation of gallic acid was performed on C18 chromatographic column with a column temperature of 20℃; the mobile phase was composed of acetic acid - McOH - DMF - H2O(2 8 30 160) with a flow rate of 0.5ml/ mm and detection wavelength of 280nm .RESULTS:
The linear range of gallic acid was 8.4-92.4?g/ ml( r = 0.9 997),the average recovery rate was 99.13% (RSD = 1.55%) .CONCLUSION:
The method developed in the present study is of high specificity .sensitivity .precision,recovery and reproducibility and it can provide a basis for the formulation of quality control method for tea pigment injection.
