The antioxidant properties and antimicrobial activity of rosemary extracts were compared to those of vine leaf extracts. The phenolics were quantified by HPLC. Rosemary extracts were stronger in reducing power than vine leaf extracts but possessed weaker superoxide anion radical (O2 ) scavenging capability. The antimicrobial activity was confirmed by the broth microdilution test using minimal i...

Simultaneous comparison of bilberry (Vaccinium myrtillus L.) and blueberry (Vaccinium corymbosum L) fruits for their anthocyanin composition, antimicrobial and antioxidant activity is reported. The aim of this study was to investigate and to compare anthocyanin composition, antimicrobial and antioxidant activity in bilberry and blueberry fruits and their skins. The investigations revealed that ...

cinnamon is the bark the cinnamomi cassia that exhibits many medical properties such as anti-cancer effect and anti-diabetic effect. moreover, because of its antioxidant activity; it can be used in food industries. many studies have already reported biological and chemical properties of the cinnamon extracted essential oil such as their antimicrobial, antifungal, antimosquito, free radical scav...

Michelia Champaca (Magnoliaceae) is a large medicinal plant which is traditionally used against a number of diseases including inflammatory conditions. Antioxidant capacity and antimicrobial activities of various extracts of Michelia Champaca Linn flowers were investigated in this study. The study was aimed at determining the antioxidant activity (reducing powers, 2, 2-diphenyl-1-picrylhydrazyl...

Diverse plants of ethnobotanic interest in Amazonia are commonly used in traditional medicine. We determined the antioxidant potential against lipid peroxidation, the antimicrobial activity, and the polyphenol composition of several Amazonian plants (Brownea rosademonte, Piper glandulosissimum, Piper krukoffii, Piper putumayoense, Solanum grandiflorum, and Vismia baccifera). Extracts from the p...

Background & Aims: Sea urchin immune responses are directly exposed to potentially pathogenic microorganisms and develop defence responses mainly based on immunocytes and humoral factors contained in the coelomic fluid. In addition, the polyhydroxylated 1, 4-naphthoquinone pigments are found to possess excellent antimicrobial, antialgal and antioxidant activities. The present ...

8-Hydroxyquinoline (8HQ) compounds have been reported to possess diverse bioactivities. In recent years, drug repositioning has gained considerable attention in drug discovery and development. Herein, 8HQ (1) and its derivatives (2-9) bearing various substituents (amino, nitro, cyano and halogen) were investigated for their antimicrobial against 27 microorganisms (agar dilution method) and anti...

In this research, we report the size-controlled synthesis and surface-functionalization of magnetite with the natural antioxidant gallic acid (GA) as a ligand, using in situ and post-synthesis methods. GA functionalization provided narrow size distribution, with an average particle size of 5 and 8 nm for in situ synthesis of gallic acid functionalized magnetite IONP@GA1 and IONP@GA2, respective...

Lupin (Lupinus termis) seeds are popularly edible and used as snacks in Sudan. The current study aimed to evaluate some biological properties of the Sudanese lupin seeds such as the phytochemical constituents, the antimicrobial and antioxidant activities. The study revealed that the methanolic extract of lupin seeds have no significant antimicrobial activity against all the tested bacteria (6 d...
