Effects of apigenin and its glycosides on UA production in cultured AML12 hepatocytes. The hepatocytes were treated with apigenin (a), vitexin (b), isovitexin (c), apigetrin (d) and rhoifolin (e) at 0 (control), 10, 30 and 100 µM for 2 h in BSS containing guanosine and inosine (100 µM each) in combination (GI mixture) as UA precursors. Each value represents mean ± SEM for 6 wells (duplicate measurement per well). Values not sharing a common letter are significantly different at P < 0.05 (Tukey’s test)
