Enantiomeric separation of substituted flavanoids by LC-DAD.


A variety of racemic flavanoids with anti-rhinovirus activity have been resolved for the first time by HPLC, using a chiral stationary phase. Baseline separation was easily obtained for racemic 4',6-dichloroisoflavan (V). The absolute configurations of two enantiomers (Va and Vb) were established by comparing their circular dichroism curves with those of… (More)
