Effects of quercetin and mono-methylated quercetin on UA production in AML12 cells. AML hepatocytes were treated with 0, 3, 10 and 30 µM querctin (a), isorhamnetin (b), tamrixetin (c), 3-O-methylquerctin (d), azaleatin (e) and rhamnetin (f) for 2 h in BSS containing guanosine + inosine (100 µM each). Each value represents mean ± SEM for six wells (duplicate measurement per well). Values not sharing a common letter are significantly different at P < 0.05 (Tukey’s test)
