Phytochemical investigation of the fruits of  Crataegus pinnatifida  Bunge led to the isolation of four pairs enantiomeric benzofuran lignans ( 1a / 1b – 4a / 4b ) including four undescribed compounds ( 1a ,  2b ,  3b  and  4b ). Their structures were determined by extensive spectroscopic methods and the absolute configurations were further determined by the comparison of experimental and calculated ECD spectra. All the enantiomeric lignans were evaluated for their inhibitory activities to tyrosinase. Among them, compound  4a  showed moderate inhibition activity (IC 50  = 0.54 mM).
