The present work evaluated the chemical composition and the DNA protective effect of the essential oils (EOs) from Lippia alba against bleomycin-induced genotoxicity. EO constituents were determined by Gas Chromatography/Mass Spectrometric (GC-MS) analysis. The major compounds encountered being citral (33% geranial and 25% neral), geraniol (7%) and trans-β-caryophyllene (7%) for L. alba specime...

Stress is closely linked by its biological mechanisms to inflammation and by its consequences to accelerated aging. Stress triggers a hormonal response along the hypothalamus-pituitary-adrenal (HPA) axis, which can disrupt the ortho/parasympathetic balance essential for a harmonious life. Proper nutrition, adequate physical activity, and limiting the harmful influence of stress play important r...

Oxidation products of terpenes (e.g. limonene) contain unidentified irritants, which may be responsible for a fraction of the reported eye and airway complaints in indoor environments. Here we report exposure to parts per billion (ppb) levels of limonene oxidation products (LOPs) and the terpene oxidation product methacrolein using blink frequency (BF) as a measure of trigeminal stimulation of ...

The aim of this study was to investigate a novel delivery system containing D-limonene and nisin by food organogel-nanoemulsion and study its effect on the antimicrobial activity. Organogel-nanoemulsion containing with D-limonene and nisin or without nisin was prepared by a homogenization method. Factors that may affect the droplet size and stability of organogel-nanoemulsion such as pressure a...

Perillyl derivatives are increasingly important due to their flavouring and antimicrobial properties as well as their potential as anticancer agents. These terpenoid species, which are present in limited amounts in plants, may be obtained via bioconversion of selected monoterpene hydrocarbons. In this study, seventeen yeast strains were screened for their ability to oxidize the exocyclic methyl...

orange peel extract solution contains mucilage flavor and three types of glycosides. limonene is one of the terpenoides in some vegetables, fruits and food; that plays as an antioxidant in juice. as it has anti-microorganism effects on some bacteria, we carried out the antifungal effects of limonene versus orange extract. in the present study the effects of orange extract and two types of limon...

essential oil of the orange peel which was extracted by hydrodistillation method showed 50 different mono- and sesquiterpenes on gc-ms analysis, in which limonene had the highest percentage (92.4%). due to various important uses of the compound, a method was developed for isolation and purification of limonene. in this method, for extra purification, a fractional distillation on vigreux column ...

Certain alkenylbenzenes (AB), flavoring chemicals naturally occurring in spices and herbs, are established to be cytotoxic and hepatocarcinogenic in rodents. The purpose of the present study was to determine the DNA damaging potential of key representatives of this class using the Turkey Egg Genotoxicity Assay. Medium white turkey eggs with 22- to 24-day-old fetuses received three injections of...
