Abstract: (314 Views)
German chamomile (Matricaria chamomilla L.) is a well-known medicinal plant that is distributed worldwide and is widely used in traditional medicine for the treatment of various diseases. In this study, the essential oil of M. chamomilla was extracted by water distillation method and its total phenol content, total flavonoid content, antioxidant activity, and antimicrobial effect were investigated. The total phenol content of the essential oil was 39.70 mg GAE/g and its total flavonoid content was 18.80 mg QE/g. The antioxidant activity of the essential oil was evaluated based on two methods of inhibiting free radicals DPPH and ABTS; the essential oil was able to inhibit free radicals DPPH (58.60 %) and ABTS (61.60 %). The antimicrobial effect of the essential oil against Bacillus cereus, Streptococcus pyogenes, Staphylococcus aureus, Shigella dysenteriae, Enterobacter aerogenes, and Salmonella typhimurium was investigated by disk diffusion agar, well diffusion agar, minimum inhibitory concentration, and minimum bactericidal concentration. The findings of the antimicrobial activity of the essential oil by the disk diffusion agar and well diffusion agar, showed that S. pyogenes and E. aerogenes were the most sensitive and resistant microbial strains to M. chamomilla essential oil, respectively. The results of this study showed that the essential oil of M. chamomilla has shown strong antioxidant and antimicrobial activity, which can be a potential candidate for the preparation of antioxidant and antimicrobial drugs.
