Fig. 4From: Isoferulic acid prevents methylglyoxal-induced protein glycation and DNA damage by free radical scavenging activityThe HPLC chromatogram of MG after reaction with IFA or AG at 1 h (a) and 24 h (b). MG was detected as 2-methylquinoxaline (2-MQ) after derivatization using o-phenylenediamine at 315 nm. 5-methylquinoxaline (5-MQ) was used as the internal standardBack to article page
