Oxidative stress and protein glycation play pivotal roles in the pathophysiology of diabetes mellitus and its vascular complications. The present study aimed to investigate the anti-glycation properties of essential oils obtained from different parts of Juniperus communis subsp. hemisphaerica. The branchlets of male tree (BMT) and branchlets of female (BFT) tree, and fruits of J. communis subsp...

Investigations have been carried out on the relative preference of U. mukerjii to four common species viz., C. maculatus, C. analis, C. chinensis and Zabrotes subfasciatus of store bruchids. Results show correspondence between the acceptance/contact ratio and the total number of eggs laid by the parasitoid for Callosobruchus species. U. mukerjii shows maximum preference on C. maculatus followed...

Achillea moschata Wulfen (Asteraceae) is an endemic species growing on the Alps and traditionally used in several medicinal remedies. For its aromatic properties, it is also collected for food purposes. Chemical content and biological activity of A. moschata oil are not extensively studied. We investigated whether the different lithological and geomorphological features of two alpine areas incl...

The essential oils of Phyllostachys heterocycla cv. Pubescens, Phyllostachys heterocycla cv. Gracilis, Phyllostachys heterocycla cv. Heterocycla and Phyllostachys kwangsiensis leaves were obtained by steam distillation. Their chemical components were separated and identified by gas chromatography/mass spectrometry (GC/MS). Meanwhile, the effect of scavenging free radicals of essential oil was a...

in this research, microwave-assisted hydrodistillation (md) with pretreatment ultrasound (us) 45 and 90 min of essential oils from fresh aegle marmelos peel were used and the results were compared with those obtained by hydrodistillation technique (hd) in terms of extraction yield/efficiency, extraction time, chemical composition and quality of the essential oil. all experiments were performed ...

Nowadays, essential oils are used in different products such as food as natural antioxidants, antibacterial and flavoring compounds (1). Essential oils are used as a replacement for chemical preservatives such as butylated hydroxytoluene (BHT) and tertiary butyl hydroquinone (TBHQ) that can threaten human health as cancer promoters (2). Nearly 3000 different essential oils are known today, and ...

Over 90% of the insect damage to cowpea seeds is caused by Callosobruchus maculatus. Although, many chemicals have proven their efficacy against C. maculatus, they adversely affect natural environment. Death non-targeted species which are enemies other pests and development resistance possible. Therefore, current study was conducted determine effect plant leaves Murraya koenigii (“Karapincha”),...

Natural products obtained from plants with biocidal activity represent an alternative and useful source in the control of biodeterioration of documentary heritage, without negative environmental and human impacts. In this work, we studied the antimicrobial activity of seven essential oils against microorganisms associated with the biodeterioration of documentary heritage. The essential oils wer...

Herbs and spices have been used since ancient times to improve the sensory characteristics of food, to act as preservatives and for their nutritional and healthy properties. Herbs and spices are generally recognized as safe (GRAS) and are excellent substitutes for chemical additives. Essential oils are mixtures of volatile compounds obtained, mainly by steam distillation, from medicinal and aro...

abstract        background and objective: peroxidases catalyze protein oxidation and lipid peroxidation. the activity of these enzymes in nerve cells is involved in causing disorders such as alzheimer's and parkinson's disease. this study investigated the effect of citrus aurantium, foeniculum vulgare and rosmarinus officinalis essential oils on activity of peroxidase enzyme.       me...
