In this study, we aimed to examine the mutagenic and antimutagenic potencies of three luteolin derivatives (luteolin-7-O-glucoside, luteolin-7-O-rutinoside and luteolin-7-O-glucuronide) by using a eukary-otic cell system, Saccharomyces cerevisiae (RS112). In the antimutagenicity assays, these luteolin derivatives showed antimutagenic effects in deletion and intrachromosomal recombination events against ethyl methanesulfonate and acridine mutagen agents. In deletion events, the highest inhibition rates for luteolin-7-O-glucoside, luteolin-7-O-rutinoside and luteolin-7-O-glucuronide against ethyl methanesulfonate were 57.6%, 58.3% and 62.5%, respectively. Likewise, the highest inhibition rates for luteolin-7-O-glucoside, luteolin-7-O-rutinoside and luteolin-7-O-glucuronide against acridin were 21.8%, 22.4% and 23.6%, respectively. Our findings showed that these luteolin derivatives have stronger antimutagenic properties against ethyl methanesulfonate compared to the acridine mutagen agent.
