BACKGROUND Use of essential oils for controlling Candida albicans growth has gained significance due to the resistance acquired by pathogens towards a number of widely-used drugs. The aim of this study was to test the antifungal activity of selected essential oils against Candida albicans in liquid and vapour phase and to determine the chemical composition and mechanism of action of most potent...

background & aim: the world production and consumption of essential oils and perfumes are increasing very fast. lippia citriodora h.b.k. is an herbal species mainly used as a spice and medicinal plant. endogenous levels as well exogenous application of plant growth regulators (pgr) could affect essential oil production and chemical compositions. experimental: to study the effect of exogenou...

in this study lemon juice were packaged at three type of packaging ( pet , pe and glass bottles ). the samples were stored ten weeks at 20 and 40 ◦c . physicochemical (ph, acidity, brix, vitamin c , so2 and formalin number ) and sensory properties of lemon juice were evaluated on every two weeks. the results showed that the two storage temperatures(20 and 40 ◦c ) had not any significant effect ...

Four essential oils in two concentrations (50 and 100%) of thyme, Thymus vulgaris; Cinnamon, Cinnamomum zeylanicum; Lemon grass, Cymbopagon flexuosus; Anise, Pimpinella anisum and formic acid (65%) were used against varroa mite, Varroa destructor infesting honey bee colonies. Results show that, formic acid and the highest concentration (100%) of tested essential oils caused effective control of...
