Silene, the largest genus of the Caryophyllaceae family, is comprised of about 700-750 species distributed over the globe [1]. Ethnobotanical evidence indicates that several Silene species have been used for medicinal purposes and are consumed as food in Anatolia, Turkey [2]. We aimed to determine antioxidant properties of water extracts from two Silene species (S. alba and S. italica). Different assays were performed to detect antioxidant properties. These are free radical scavenging (ABTS and DPPH), reducing power (CUPRAC and FRAP), phospehomolybdenum and metal chelating. Also, total phenolic and flavonoid contents were calculated for each extracts. S. alba contained higher level of phenolics (26.94 mgGAE/g extract) than S. italic (24.00 mgGAE/g extract). Also, S. alba extract displayed considerable antioxidant abilities (78.95 mgTE/g for DPPH; 113.10 mgTE/g for ABTS; 107.43 mgTE/g for CUPRAC and 123.43 mgTE/g for FRAP). The presented results could be opened new avenues for designing novel functional formulations from tested Silene species.
