Sixteen antioxidative active compounds isolated from the EtOAc layer of MeOH extracts of kochujang, Koreanfermented red pepper paste, were structurally elucidated as fumaric acid, methyl succinate, succinic acid furan-2-yl estermethyl ester (gochujangate, a novel compound), 2-hydroxy-3-phenylpropanoic acid, 3,4-dihydroxybenzoic acid, 2,3-dihydroxybenzoic acid, 2,4-dihydroxybenzoic acid, 6,7-dihydroxy-2H-chromen-2-one (esculetin), caffeic acid, cis-p-coumaricacid, trans-p-coumaric acid, daidzin, genistin, apigenin 7-O-β-D-apiofuranosyl(1→2)-β-D-glucopyranoside, apigenin 7-O-β-D-glucopyranoside, and quercetin 3-O-α-L-rhamnopyranoside by mass spectrometry (MS) and nuclear magnetic resonance(NMR) experiments. These compounds were analyzed for the first time as antioxidants from kochujang.
