MAHDIAN, Fourough; MAHBOUBI, Mohaddese; RAHIMI, Ebrahim  and  SHAD, Maryam Moslehi. Chemical composition, antimicrobial and antioxidant activities of Echinophora platyloba essential oil. Infect. [online]. 2017, vol.21, n.3, pp.176-181. ISSN 0123-9392.


Echinophora platyloba is traditionally used as antimicrobial agent in order to preserve the home-made products from deterioration. The aim of this study was to evaluate chemical composition of essential oil, antimicrobial and antioxidant activity of E. platyloba essential oil from Shahr-E-Kord city, Chaharmahal and Bakhtiari Province.

Materials and methods:

chemical composition of E. platyloba essential oil by GC and GC-MS techniques and evaluate its antibacterial effect against Staphylococcus aureus, Salmonella enterica and Helicobacter pylori by disc diffusion and micro broth dilution assays. The antioxidant activity of E. platyloba essential oil was evaluated by ABST radicals. β-ocimene and α-caryophyllene were the main components of E. platyloba essential oil. The essential oil showed the promised antibacterial activity against S. aureus, followed by S. enterica and H. pylori. The antioxidant activity evaluation of essential oil showed the IC50 of 0.32 mg/ml that was higher than the IC50 of ascorbic acid (0.20 mg/ml).

In conclusion

, E. platyloba essential oil has β-ocimene and α-caryophyllene chemotype and its use as antioxidant and antibacterial agents is recommended as its traditional uses.

Keywords : E. platyloba essential oil; β-ocimene; α-caryophyllene; antimicrobial; antioxidant.
