This study focused on five different subspecies of Portuguese Daucus carota L., to identify the main compounds in essential oils umbels from each subspecies. The isolation was performed by hydrodistillation methods followed further composition analysis gas chromatography-mass spectrometry, ultimately demonstrating that had major compounds. concluded found subsp. maritimus were geranyl acetate, ...

Vitamin E refers to a family of compounds that function as lipid-soluble antioxidants capable of preventing lipid peroxidation. Naturally occurring forms of vitamin E include tocopherols and tocotrienols. Vitamin E in dietary supplements and fortified foods is often an esterified form of α-tocopherol, the most common esters being acetate and succinate. The vitamin E esters are hydrolyzed and co...

background: diabetes mellitus is a chronic disease. decreasing postprandial hyperglycemia by retarding glucose absorption through inhibiting carbohydrates digesting enzymes (α-amylase and α-glucosidase) is one of many approaches used for the management of this disease. this study was aimed at evaluating the normoglycaemic potential of helianthus annuus leaf. methods: the effect of the in vitro ...

In order to qualitative and quantitative study on essential oil, obtained from leaf and peel of Citrus aurantium L. cultivated in North of Iran (Sari city) the leaves and fruits were gathered on April and November 2002, respectivelly. Clevenger apparatus was used for hydro-distillation extraction in order to provide the oil of leaf and peel of Citrus aurantium L. The outputs of each essential o...

Abstract Thirty-one samples of essential oils used both in perfumery and aromatherapy were purchased to business-to-consumers suppliers submitted standard gas chromatography-based analysis their chemical composition. Their compliance with ISO AFNOR standards was checked revealed, although ranges are relatively loose, that more than 45% the analyzed failed pass test 19% diluted solvents such as ...

The aim of this study was to test the quality (physicochemical and sensory odor properties) bioactivity (antimicrobial antioxidant activities) essential oils (EO) obtained from most frequently cultivated lavender lavandin varieties in Serbia, whose cultivation areas were previously reserved for warmer climates, outside agroecological region Serbia. Seven EO true lavenders (L. angustifolia Mill....

dl-phenyl alanine labeled with carbon-14 in the α-position has been synthesized from ethyl[2-14c] acetate as part of a 6-step sequence.

BACKGROUND The current chemotherapy for cutaneous leishmaniosis (CL) has a series of drug limitations such as toxic side effects, long duration, high costs and drug resistance, which requires the development of new drugs or effective alternatives to the CL treatment. Essential oils (EOs) are complex mixtures of secondary metabolites from various plants. It has been shown that several EOs, or th...
