| Abstract: | Preparation, homogeneity, stability and certification of reference material of gallic acid were studied. Highly purified reference material of gallic acid was prepared from an industrial grade product of gallic acid by recrystallization. The chemical structural formula of gallic acid was identified by IR, NMR and thermogravimetric analysis. The content of gallic acid in reference material was measured by HPLC with area normalization method. The reference material of gallic acid passed the test of homogeneity, and it was stable within 15 months. According to certification of six laboratories, the standard value of gallic acid content was 99.96%±0.10%. |
