- چکیده:
- چکیده انگلیسی: In the present study, we reported the essential oils chemical composition and antibacterial activities of the aerial parts of Ajuga chamaecistus Ging. ex Benth. Subsp. Scoparia (Boiss.) Rech.f. thatwere collected duringMay 2013 and April 2014 and extracted by SDE (simultaneous distillation–extraction) and Clevenger apparatus. GC/MS analysis of the plant essential oils led to the identification of chemical composition of its oils. The main constituents of the essential oils in two SDE (simultaneous distillation–extraction) and Clevenger apparatus were β-Pinene (23.5%), α-Pinene (6.9%), Limonene (10.8%), Linalool (8.3) and Eugenol (7.7%). Essential oil was tested for their antibacterial activities using Gram-negative bacteria, Gram-positive bacteria. The plant was screened for its antibacterial activity and showed antibacterial activity against P. aeruginosa, E. coli, K. pneumoniae, P. vulgaris, S. paratyphi, B. subtilis, S. aureus, S. epidermidis and S. dysenteriae.

- چکیده:
- چکیده انگلیسی: Objective: Many species of plants present noticeable potency against human bacterial and fungal pathogens.
Materials and Methods: In the current study, antimicrobial activity of the fresh fruits of 4 cultivars (A to D) of Malus domestica cultivated in the Qamsar area of Kashan, Iranwas investigated. The disk diffusion and minimal inhibitory concentration (MIC) evaluation antimicrobial activity tests were performed.
Results: The samples showed moderate antimicrobial activities with inhibition zones from 11 to 16 mm in these tests. Cultivar D with inhibition zones of 16, 14, and 12 mm for E. coli, S. epidermidis and K. pneumoniae, respectively exhibited the best results in these tests. Cultivar A also showed a zone of inhibition of 11 mm against P. aerouginosa.
Conclusion: Moderate antimicrobial activities were observed for the studied apple cultivars.

- چکیده:
- چکیده انگلیسی: Objective: Antioxidants are considered as the main factors in the inhibition of unwanted oxidation reactions.
Materials and Methods: In this research the antioxidant potential of the fresh fruits of 4 cultivars (A to D) of Malus domestica (M. domestica) cultivated in the Kashan, Qamsar area was evaluated. The antioxidant activity of the samples were evaluated using two complementary antioxidant assays: 2, 2-diphenyl-1-picrylhydrazyl (DPPH) and β-carotene/linoleic acid tests and the results were compared with the synthetic standard antioxidant butylated hydroxytoluene (BHT).
Results: Total phenolic contents of the samples are also estimated by Folin-Ciocalteu's phenol test. In both DPPH β-carotene/linoleic acid tests in the concentration of 2 mg/ml, only samples from cultivar A showed moderate antioxidant activity with 63.92±0.42 and 6.02±0.03 inhibition percentages, respectively and other samples were weakly active.
Conclusion: The Folin-Ciocalteu's phenol test was also showed very little phenolic compounds for the fruits. In conclusion, weak antioxidant activity was estimated for the studied apple cultivars.- انتشار مقاله: 17-11-1390
