Polyphenolic Content, Antioxidant Potential and Antimicrobial Activity of Satureja boissieri

摘要

Antioxidant activities of Satureja boissieri extracts were detected by using specificin vitro techniques. Standard antioxidant compounds such as ascorbic acid, BHA (ButylatedHydroxyanisole) and BHT (Butylated Hydroxytoluene) were used to compare with the resultsobtained from ethanol and water extracts of the plant samples. Both extracts presented highantioxidant actions on ABTS cation radical and DPPH free radical scavenging methods.Furthermore, the antimicrobial activity of S. boissieri was defined by using three fungi species,three Gram-positive and four Gram-negative bacteria species. The reducing power antioxidantactivities of samples were measured by CUPRAC and FRAP techniques. Also, phenolic compoundsof S. boissieri leaves were identified by UHPLC-ESI-MS/MS. The high concentration of hesperidin(5051 ± 247 ppb) and rosmarinic acid (4364 ± 214 ppb) was characterized quantitatively.According to the results, high phenolic content can be thought of as one of the responsible parametersfor effective biological activity. Also, its flavonoid and phenolic contents are good natural sourcesfor using in the food industry and pharmacological process.
