HPLC elution profiles of the enzyme reaction products of C. microcarpa QNS and ACS.
A–D, enzyme reaction products of C. microcarpa (Cm) ACS and QNS from N-methylanthraniloyl-CoA (A), 4-coumaroyl-CoA (B), benzoyl-CoA (C), and hexanoyl-CoA, and malonyl-CoA (D). Note that by acid treatment naringenin chalcone is converted to racemic naringenin (5,7,4′-trihydroxyflavanone) through a nonstereospecific ring-C closure.
