(±)-5-Hydroxy-1,7-bis-(4'-hydroxyphenyl)-3-heptanone (2a), (±)5- hydroxyl-1-(4'-hydroxyphenyl)-7-phenyl-3-heptanone (2b), (±)-5-hydroxy-7- (4'-hydroxyphenyl)-1-phenyl-3-heptanone (2c), and (±)-5-hydroxy-1,7- bis(phenyl)-3-heptanone (2d) have been synthesized to study the structure- activity relationship regarding digestibility inhibition in vitro in cow rumen fluid. The activities were compared with the activity of chiral (S)-2a and its glucoside platyphylloside (1), isolated from Betula pendula. Compound 2a was slightly less active, 2b and 2c were more active, and 2d was less active than (S)-2a and platyphylloside.
