Fig. 5From: Protective role of Clitoria ternatea L. flower extract on methylglyoxal-induced protein glycation and oxidative damage to DNAThe HPLC chromatogram of methylglyoxal (MG) after reaction with Clitoria ternatea flower extract (CTE, 0.125–1 mg/mL) and aminoguanidine (AG, 1 mg/mL). 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
