Abstract: OBJECTIVE: To optimize chromatographic conditions for determination of gallic acid contents in Phyllanthus emblica L. from different regions. METHODS: Determination of gallic acid in Phyllanthus emblica L. in different regions was performed on an Eclipse plus C18 (25 μm, 4.6 mm×250 mm). The mobile phase was Acetonitrile-0.2% phosphoric acid solution (5:95). The elution was in same degree. The current speed was 1.000 mL/min. The detection wave length was 273 nm and the determination of linear regression equation used standard curve method. The column temperature was 30 degrees Celsius. RESULTS: Gallic acid had a good linear relationship in the range of 13.010-130.104 g/mL (R2=0.999 4). It also had good precision (RSD=0.08%), good stability (RSD=0.29%) and general reproducibility (RSD=4.23%). The content of gallic acid in the three batches of Phyllanthus emblica L. were higher than Chinese Pharmacopoeia national standard of 1.2%. CONCLUSION: The method for the determination of gallic acid in Phyllanthus emblica showed strong specificity and good precision. In addition, the results were accurate and reliable.
