Fig. 5From: Polyphenols from the extract and fraction of T. indica seeds protected HepG2 cells against oxidative stress a-c Chromatograms of polyphenolic standards (a), methanol seed extract of T. indica (b) and fraction F3 (c). Individual retention times and peak identification of the polyphenols in the extracts were compared with the chromatogram of a standard mixture of polyphenols analyzed with UHPLC 1290 Infinity LC system. The polyphenols were detected at a wavelength of 280 nm. 1: gallic acid; 2: catechin; 3: procyanidin B2; 4: chlorogenic acid; 5: epicatechin; 6: caffeic acid; 7: vanillic acid; 8: p-coumaric acid; 9: ferulic acid; 10: chloramphenicol; 11: rutin; 12: myricetin; 13: morin; 14: ellagic acid; 15: cinnamic acid; 16: naringenin; 17: quercetin; 18: luteolin; 19: apigenin; 20: isorhamnetin; 21: kaempferolBack to article page
