Exploration of antimicrobial potential of essential oils ofCinnamomum glanduliferum, Feronia elephantum, Bupleurum hamiltoniiandCyclospermum leptophyllumagainst foodborne pathogens

Abstract

Context: Cinnamomum glanduliferum (Wall.) Meissn. (Lauraceae), Feronia elephantum Correa (Rutaceae), Bupleurum hamiltonii Balak (Apiaceae) and Cyclospermum leptophyllum (Pers.) Sprague ex Britton & P. Wilson (Apiaceae) are common species found in Northwest Himalaya and are widely used as folk medicine. The study became more interesting because hitherto there are no reports on the antimicrobial screening of these species with specific chemical composition.Objective: The antimicrobial potential of the essential oils of C. glanduliferum, F. elephantum, B. hamiltonii and C. leptophyllum against some commonly occurring foodborne pathogenic and spoilage bacteria was explored in this study. Materials and methods: Antimicrobial screening studies of essential oils were performed against some Gram-positive and Gram-negative bacterial strains using broth-dilution methods. Each essential oil was prepared by serial double dilution method to get final concentrations ranging from 0.85-440.0 mg/ml in a 96 microtiter plate. Results: The in vitro studies revealed that C. glanduliferum oil was very active against Gramnegative bacteria, A. salmonicida (MIC 1.72 mg/ml), E. coli (MIC 3.43 mg/ml), and P. aeruginosa (MIC 3.43 mg/ml) as compared to the standards gentamicin and kanamicin. Oil of C. leptophyllum exhibited better inhibitory activity profile against Gram-positive S. aureus (MIC 3.43 mg/ml) and Gram-negative E. herbicola (MIC 1.72 mg/ml) and P. aeruginosa (MIC 3.43 mg/ml) as compared to the standards. Discussion and conclusion: These results reveal that these essential oils may be used in the treatment of diseases caused by the foodborne pathogenic and spoilage bacteria. Their importance as potential medicinal agents is based on the antimicrobial findings.

Chemical Characteristics, Antimicrobial, and Cytotoxic Activities of the Essential Oil of Egyptian Cinnamomum glanduliferum Bark

“…The results of MIC ( Table ) confirmed the antimicrobial activity of oil quantitatively. The tested oil is highly effective against E. coli with MIC value of 0.49 μg/ml (more than gentamycin in which MIC equaled to 0.98 μg/ml), which agreed with Singh et al . who reported that the extracted essential oil from Indian C. glanduliferum is very active against E. coli ( MIC 3.40 mg/ml).…”

“…Cinnamon essential oil and its constituents are known to possess various antimicrobial activities. For example, Cinnamomum zeylanicum bark and Cinnamomum glanduliferum leaves exerted antimicrobial activities against both Gram ‐negative and Gram ‐positive bacteria . The other biological activity of cinnamon oil is its anticancer effect.…”

Essential oil ofPsidium cattleianumleaves: Antioxidant and antifungal activity

“…These components are chemically derived from terpenes and their oxygenated derivatives (Solórzano-Santos & Miranda-Novales, 2012). EO possesses many pharmacological effects described, such as antioxidant (Victoria et al, 2012;Wang et al, 2013), antimicrobial (Singh et al, 2013;Stefanakis et al, 2013), and antinociceptive (Amorim et al, 2009).…”
