Abstract

In this paper, using capillary zone electrophoresis method determined gallic acid content in Paeonia lactiflora Pall. Under the condition of buffer solution containing 20 mmol/L Na2B4O7, effective separation of components to be tested was realized. Measured content of gallic acid in Paeonia lactiflora Pall was 1.15 mg/g (RSD=4.28%) (n=6), the average recovery was 88.48% (n=5). This method is simple and fast.
