Objective: The objective of the present study was to evaluate antioxidant and free radical scavenging activity of various extracts of Rose flower petals. Methods: Chloroform, acetone, ethan...

Merkl R., Hrádková I., Filip V., Šmidrkal J. (2010): Antimicrobial and antioxidant properties of phenolic acids alkyl esters. Czech J. Food Sci., 28: 275–279. Some phenolic acids alkyl esters (methyl, ethyl, propyl, butyl and hexyl) and determine their antioxidant and antimicrobial activities were prepared. The antimicrobial activity against the tested microorganisms escherichia coli DMF 7503, ...

PURPOSE This research paper presents antioxidant and antimicrobial activities of Pedicularis sibthorpii and Pedicularis wilhelmsiana which grow in Azerbaijan/Iran with claimed a lot of therapeutic effects. METHODS DPPH assay and agar well diffusion method were carried out to determine antioxidant and antimicrobial activities respectively. RESULTS Methanolic extract showed better antioxidant...

The in vitro antimicrobial and antioxidant activities of the exopolysaccharide (EPS) extracted from yoghurt starter were investigated. Antimicrobial activity tests were carried out using disc diffusion methods with Escherichia coli, Staphylococcus aureus and Streptococcus D, Proteus spp and the yeast of Candida albicans. The antioxidant properties were evaluated using the test of DPPH free radi...

BACKGROUND The plants belonging to the Ocimum genus of the Lamiaceae family are considered to be a rich source of essential oils which have expressed biological activity and use in different area of human activity. There is a great variety of chemotypes within the same basil species. Essential oils from three different cultivars of basil, O. basilicum var. purpureum, O. basilicum var. thyrsiflo...

Background and objectives: Lamiaceae members have long been used in Iranian Traditional Medicine (ITM) for their various medicinal properties. The main objective of this study was to evaluate the antioxidant capacity and antimicrobial activity as well as the total phenolic content (TPC) of the various extracts and fractions of two Iranian endemic Micromeria (M. persica and M. hedgei). Methods: ...

Essential oils mainly used in food industry for preservation are a main source of many bioactive compounds, which have antioxidant property, antimicrobial activity and also flavoring agents. Natural preservatives products suitable to be order extend the shelf-life maintain quality foods. In this preservative application, more alternative approaches is required meet consumer demands, establish p...

The essential oil (EO) from dried ground powder leaves and stems of Thymua danesis was extracted using hydrodistillation (HD), ohmic extraction (OE), ultrasound-assisted HD and ultrasound-assisted OE methods. Then, the antioxidant, antimicrobial, and sensory properties of the EO were investigated both in vitro and in food systems. Thyme EO extracted by ultrasound-assisted HD method had promisin...

Background: The application of natural antimicrobial and antioxidant agents in food pharmaceutical products has recently become a trend due to the high demand for them from consumers. Postbiotics are bioactive compounds that produced when healthy bacteria gut ferment fiber. Objectives: This study aimed compare antibacterial properties postbiotics 5 different lactic acid (LAB) including Lactipla...
