Abstract: Hydroxy in dihydromyricetin(DMY)was esterified with lauroyl chloride and dihydromyricetin laurate (DMYL) was synthesized in this investigation. The structure of DMYL was tested using infrared spectrogram. The antioxidation capability of DMYL for lard was found better than DMY after comparison between DMY and DMYL in lard system. DMY acted as stimulative for oxidation in lard during late period while DMYL stably continued the function of antioxidation in lard for longer time. The investigated optimal adding amount of DMYL for lard system is 1.0mmol/L through investigation antioxidation capability of DMYL with different amount.

Key words: dihydromyricetin, dihydromyricetin laurate, antioxidation activity, lard
