Occurrence of antibiotic resistance in pathogenic strains of bacteria caused researchers to search for substitution of chemical antibiotics with natural products derived from plants. High levels of antibacterial and anti-oxidant materials make Calendula offi cinalis good for synthesis of antibacterial drugs. The present investigation was carried out to study the hemical components and antibacterial effects of the C. offi cinalis essential oil. Flowers of the C. offi cinalis were collected and transferred to the laboratory. Essential oil was extracted and the gas chromatography was applied to study the chemical components. Antibacterial effects of C. offi cinalis was studied using the disk diffusion method. 1,8-cineole (30.456%), -Terpinene (25.547%), Terpinolene (4.584%), -Terpineol (4.490%) and Trans--ocinene (4.153%) were the most commonly detected components in the essential oil of the C. offi cinalis. Percent of chemical components had signifi cant differences (P < 0.05). C. offi cinalis harbored the highest antibiotic effects on the Gramnegative bacteria (P < 0.05). The highest zone of inhibition was seen for the E. coli (13.31±1.24 mm) and P. aeruginosa (10.22±0.83 mm). The lowest zone of growth inhibition was seen for the S. aureus (3.14±0.27 mm). Statistically signifi cant differences were seen between the types of bacteria and antibiotic effects of C. offi cinalis essential oil (P < 0.05). Careful prescription of antibiotics can control the occurrence of antibiotic resistance in pathogenic bacteria. We recommended use of C. offi cinalis essential oil as an anti-E. coli and P. aeruginosa agent.
