is an indigenous plant which is frequently used as a spice in Avraman-Kurdistan region of Iran. The present study aimed to investigate the chemical composition, antimicrobial and antioxidant properties of the . In addition, rosmarinic acid and total phenolic content of was assessed by spectrophotometric method and HPTLC. The essential oil and methanolic extract were isolated by hydrodistillation and maceration methods, respectively. A total of 32 compounds representing 98.6% of the essential oil were identified by GC-MS and GC-FID. The main constituents were -pentacosane (23.8%), spathulenol (11.5%), β-bourbonen (11.3%) and-docosane (11.0%). The antibacterial activity of samples were carried out by disc diffusion method and evaluate the minimal inhibitory concentration (MIC) essential oil and methanolic extract were found to be effective against , and . The highest scavenging activity was found for methanolic extract of (21.58 µg/mL) and the total phenolics of methanolic extract of was 95.3 mg GAE/g. The rosmarinic acid content of methanolic extract was 0.83 mg/g plant. Antioxidant activity and rosmarininc acid content of suggests that the essential oil and methanolic extract of has great potential for application as a natural antimicrobial and antioxidant agent to preserve food.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
