High performance liquid chromatography (HPLC) analysis of the reaction products after modification of resveratrol. a HPLC profile of standard resveratrol. b HPLC profile of reaction products from B-RS3 strain. P1 and P2 were identified to be p-coumaric acid and resveratrol, respectively. c HPLC profile of reaction products from BL21 strain harboring ROMT9. P3 was determined to be pterostilbene. d HPLC profile of reaction products from BL21 strain harboring SOMT2. P4 was identified to be 4-methoxyresveratrol. e HPLC profile of reaction products from BL21 strain harboring HpaBC. P5 was identified to be piceatannol. f HPLC profile of reaction products from BL21 strain harboring SOMT2 and HpaBC. P6 and P7 were determined to be piceatannol and rhapontigenin, respectively. g HPLC profile of reaction products from BL21 strain harboring ROMT15 and HpaBC. P8 was determined to be isorhapontigenin. All the reaction products were purified and their structures were determined using nuclear magnetic resonance spectroscopy (See Materials and methods)
