Abstract:
      The 70% ethanol solution extract of peony seed shell was extracted by ethyl acetate to obtain peony seed shell ethyl acetate extract. The ethyl acetate extract was separated by silica gel column chromatography. The resveratrol isolated was identified and characterized by high performance liquid chromatography (HPLC), ultraviolet spectroscopy (UV), infrared spectroscopy (IR) and nuclear magnetic resonance spectrum (NMR). The results showed that the resveratrol monomer was obtained with higher purity of 96.25%.
