Abstract:
[Objective] To develop an HPLC method for determining Gallic acid in Milin Capsules.[Method] The contents of Gallic acid were determined by HPLC.Agilent1200 HPLC.Chromatography column was ZORBAXSB-C18(4.6?250mm,5?m);mobile phase:methanol-0.2% phosphoric(6∶94);flow rate was 1.0ml/min;UV detection wave length was 270nm.[Results] The average recovery of Gallic acid was 99.10%,RSD was 1.07%.[Conclusion] This method was simple,quick,stable,accurate,can be used as a method for determining Gallic acid in Milin Capsules.
