The biological effects of soy isoflavones have attracted considerable interest in recent years, leading to numerous studies on dietary intake and epidemiology. (−)‐( S )‐Equol ( 3 ) is a metabolite produced in vivo from the isoflavone daidzein, a kind of soy phytoestrogen, by the action of gut microflora. It has higher biological activity than its precursor. Here, we wish to report the isolation and first X‐ray crystal structure of 3 from the feces of rats fed a soy‐isoflavone‐containing diet.
