background: this study aimed at investigation of the chemical composition, antimicrobial activity, and antioxidant properties of clove, cumin, origanum, and anise essential oils (eos). methods: chemical compositions of the eos were identified using gas chromatography/mass spectrometry (gc/ms). the antibacterial activities of eos against four important food-borne bacteria were assessed by disc d...

honey is a popular food product produced by honey bees that it is a well-known antimicrobial and antioxidant activity. floral origin of honey plays an important role on its biological properties.this research was carried out to evaluate the antibacterial and antioxidant activity of four sample honey with different floral origin collected from the bee hive in the golestan province in north of ir...

The present study was carried out to evaluate the antimicrobial and antioxidant activities of methanol extract of Careya arborea (MECA) stem barks (Myrtaceae) in various in-vitro systems. Antimicrobial activities of MECA were carried out using disc diffusion methods with Gram positive and Gram negative bacteria and some fungal species. MECA showed broad-spectrum antimicrobial activity against a...

Chemical characteristics, fatty acid composition, antioxidant and antimicrobial activities ofPrunus armeniaca kernel oil were evaluated in this study. The hexane extracts of kernel of P.armeniaca, which were collected from northwestern Iran, were obtained by Soxhlet apparatus.The fatty acids were derived to methyl esters and determined by gas chromatography/flameionization detector (GC/FID) and...

BACKGROUND Scrophularia striata (Scrophulariaceae family) is an herbaceous plant that is traditionally used for treatment of microbial infections. OBJECTIVES Antimicrobial and antioxidant activity of different extracts (methanolic, ethanolic, aqueous and ethyl acetate) from S. striata aerial parts was evaluated. MATERIALS AND METHODS The antimicrobial activity of different extracts from S. ...

Hyssopus of­ficinalis L. is one of the most important medicinal plants. Medicinal herbs are contaminated by microorganisms. Conventional methods for reducing of microbial loads such as ethylene oxide, propylene oxide and also use of steam are hazardous and instead, non-thermal process such as microwave and gamma radiation are being used widely in order to eliminate the microbial contaminations ...

TLC screening and Evaluation of antioxidant, antibacterial activity of Onopordon macrocephalum by bioautography methodOnopordon known as scotch thistle is a medicinal plant of the Asteraceae family that is widely distributed in Europe and Asia, also it has many valuable medicinal properties as hypotensive and antitumor. Thin layer chromatography (TLC) is wildly used in natural product ext...

 Background: Oxidation of lipids causes reduction of different properties of products that contains lipids. Nowadays, there is a growing demand for the natural antioxidants due to the harmful effects of synthetic antioxidants such as BHA, BHT and TBHQ. Objective: In this study, extract of aerial parts of Echinacea purpurea L. was used instead of synthetic antioxidants in cake then, ant...

In the present investigation the acetone extracts of three marine macroalgae Laurentia obtusa, Codium elongatum and Cutleria multifida were tested for antioxidant, antimicrobial and cytotoxic potential. Antioxidant activity was evaluated by free radical scavenging, superoxide anion radical scavenging and reducing power. C. elongatum extract had most potent free radical scavenging activity (IC50...

The current study evaluated the general toxicity, antioxidant, antimicrobial, and cytotoxic activity of extracts obtained from the rhizomes of Eremostachys azerbaijanica (Labiatae) as well as analyzed the potent extracts using GC-MS. Extracts of E. azerbaijanica in n-hexane, dichloromethane (DCM) and methanol (MeOH) were prepared using a Soxhlet apparatus. The antioxidant activity of the extrac...
