Chemical composition, antioxidant and antibacterial properties of Bene (Pistacia atlantica subsp. mutica) hull essential oil

Abstract

The tree Pistacia atlantica subsp. mutica, namely Bene, is widely distributed in Iranian mountains. Recent studies revealed that the oil of Bene was stable, even more stable than sesame oil, with antioxidant properties. This can give versatile applications for the oil. The volatile composition of this oil has not chemically been investigated so far. In this study, sixty three compounds were identified in the essential oil (EO) of Bene hull. The major components were determined to be α-pinene (20.8 %), camphene (8.4 %), β-myrcene (8.2 %) and limonene (8 %). Antioxidant activities of the essential oil from Bene hull were evaluated by using 2, 2′-diphenyl-1-picrylhydrazyl (DPPH) free radical-scavenging, ferric reducing antioxidant power (FRAP), β-carotene bleaching test, thiobarbituric acid reactive species (TBARS) and Rancimat assays. The Bene essential oil exhibited significant antioxidant activities in FRAP and TBARS assays as compared with positive controls. In addition, the oil was evaluated for its antimicrobial activity against both Gram positive (Staphylococcus aureus) and Gram negative (Escherichia coli) bacteria. It showed significant antibacterial activities against S. aureus and E. coli with minimum inhibitory concentration (MIC) values of 6 and 12.5 μg/mL, respectively.

“…The cuvettes were thermostated at 50°C between measurements. The average percent of inhibition was calculated by the following formula [19,20].…”

Effects of Pistacia atlantica resin oil on the level of VEGF, hydroxyproline, antioxidant and wound healing activity in STZ-induced diabetic rats

“…α-Pinene was reported as major constituents of Pistacia atlantica resin oil and has very low toxicity [10]. Rezaie and coworkers have demonstrated that Pistacia atlantica hull oil has free radical scavenging activity which was comparable to α-tocopherol in vitro, and this confirmed that Pistacia atlantica acts against oxidative stress [26]. Finally, consistent with these studies we showed that Pistacia atlantica resin oil has potent antioxidant activity and also we showed that antioxidant capacity of Pistacia atlantica resin oil in diabetic model is still present which was not reported before.…”

Effect of Pistacia Atlantica Resin Oil on Anti-Oxidant, Hydroxyprolin and VEGF Changes in Experimentally-Induced Skin Burn in Rat

“…have reported that P. atlantica oil has remarkable antioxidant activities compared with positive control. 14 Koizumi et al . showed that severe burn damage cause promotion of free radicals which in turn result in vasodilatation and SOD can act as a protective factor against vasodilatation.…”

“…15 Also other studies reported antimicrobial activity of P. atlantica oil. 14 , 25 Therefore, P. atlantica resin oil in addition to increase antioxidants also has antimicrobial properties and it reduce the chance of infection and accelerate the process of wound healing.…”

“…16 Also other studies were approved antioxidant activity of P. atlantica. 12 , 14 It have been proved that P. atlantica have used for treatment of digestive diseases and also traditionally used for treatment of disorders such as colitis, gastrointestinal problems, kidney, heart and liver complications. 9 , 10 Other studies reported antifungal, antiparasite and antibacterial activity of P. atlantica.…”
