In this study, the total phenol and flavonoid contents and antioxidant activities of dried leaves and fresh and dried tubers of Leontice armeniaca and L. leontopetalum were determined using ferric reducing antioxidant power (FRAP), reducing power and superoxide radical scavenging percentage. The results revealed that in both species, the content of total phenolic, total flavonoid and FRAP of leaf were greater than tuber. The order of total phenolic and total flavonoid contents and FRAP of leontopetalum was significantly higher than armeniaca (P
