Abstract
Arils from six pomegranate (Punica granatum L.) varieties grown in the Mediterranean region of Turkey were tested for their antimicrobial properties by the agar diffusion and minimum inhibitory concentration (MIC) methods against seven bacteria: (Bacillus megaterium DSM 32, Pseudomonas aeruginosa DSM 9027, Staphylococcus aureus Cowan 1, Corynebacterium xerosis UC 9165, Escherichia coli DM, Enterococcus faecalis A10, Micrococcus luteus LA 2971), and three fungi (Kluvyeromyces marxianus A230, Rhodotorula rubra MC12, Candida albicans ATCC 1023). It has been observed that the pomegranate aril extracts had antimicrobial effect on all microorganisms, giving inhibition zones ranging in size from 13 to 26 mm. The MIC values for active pomegranate extracts ranged between 30 and >90 µg/mL. The results obtained appeared to confirm the antimicrobial potential of the Punica granatum varieties.
Highlights
The pomegranate, Punica granatum L., is one of the oldest known edible fruits
We aimed to evaluate the correlations between responses by microorganisms and pomological and phytonutrient properties such as total phenolic content (TP), total antioxidant capacity determined by TEAC (Trolox Equivalent Antioxidant Capacity) and FRAP
A summary of these characteristics are presented in Table 1 to allow evaluation of possible correlations with the antimicrobial activities seen in this work
Summary
The pomegranate, Punica granatum L., is one of the oldest known edible fruits. This fruit is mentioned in the Bible and Koran and is often associated with fertility. Punica granatum L. has been widely used by traditional medicine in America, Asia, Africa and Europe for the treatment of different types of diseases [2,3,4,5]. The fruits of Punica granatum (pomegranate) have been used to treat acidosis, dysentery, microbial infections, diarrhoea, helminthiasis, haemorrhage, and respiratory pathologies [6]. This species appear to have interesting antiviral activity
