Antioxidant and chemopreventive properties of polyphenolic compounds derived from Greek legume plant extracts
(2008)Recently, phytochemical compounds present in legumes have gained a lot of interest because they are considered to be possible chemopreventive agents. In the present study, 14 polyphenolic compounds were extracted and ... -
Antioxidant effects of whey protein on muscle C2C12 cells
(2014)In the present study, the in vitro scavenging activity of sheep whey protein against free radicals, as well as its reducing power were determined and compared with that of beef protein, soy protein and cow whey protein. ... -
The application of an improved method for trans-resveratrol to determine the origin of Greek red wines
(2001)A rapid and sensitive method has been developed for the determination of trans-resveratrol in wine. This method consists of a solid phase extraction step followed by a rapid HPLC quantification step (30 min). The improvement ... -
Biotechnology for the production of essential oils, flavours and volatile isolates. A review
(2010)Various applications of biotechnological methods for the production of volatile compounds useful to the food and pharmaceutical industries are discussed. The yields obtained from intact or genetically modified plants are ... -
Botanical Nematicides: A Review
(2012)Despite the uselfuness of nematicidal compounds in agricultural practices, some serious concerns are raised today about their excessive use leading to enhancement of biodegradation mechanisms in soil expressed as lack of ... -
Branched-chain sugar nucleosides: stereocontrolled synthesis and bioevaluation of novel 3 '-C-trifluoromethyl and 3 '-C-methyl pyranonucleosides
(2015)A new series of 3 '-C-trifluoromethyl- and 3 '-C-methyl-beta-D-allopyranonucleosides of 5-fluorouracil and their deoxy derivatives has been designed and synthesized. Treatment of ketosugar 1 with trifluoromethyltrimethylsilane ... -
A concise synthesis of 3-fluoro-5-thio-xylo- and glucopyranoses, useful precursors towards their corresponding pyranonucleoside derivatives
(2008)The chemical synthesis of 1,2,4-tri-O-acetyl-3-deoxy-3-fluoro-5-thio-D-xylopyranose, 1,2,4,6-tetra-O-acetyl-3-deoxy-3 -fluoro-5-thio-alpha(-D-glucopyranose and their corresponding nucleosides of thymine is described. ... -
Cytogenetic effects of grape extracts (Vitis vinifera) and polyphenols on mitomycin C-induced sister chromatid exchanges (SCEs) in human blood lymphocytes
(2007)In the present study, the effects of extracts and polyphenol-rich fractions as well as monomer polyphenols identified in them, from both red and white grapes, on mitomycin C (MMC) induced sister chromatid exchanges (SCEs) ... -
Degradation and Adsorption of Pesticides in Compost-Based Biomixtures as Potential Substrates for Biobeds in Southern Europe
(2010)Biobeds have been used in northern Europe for minimizing point source contamination of water resources by pesticides. However, little is known regarding their use in southern Europe where edaphoclimatic conditions and ... -
Dissipation of teflubenzuron and triflumuron residues in field-sprayed and cold-stored pears
(1999)Dissipation of residues of benzoylurea insecticides teflubenzuron (TFB) and triflumuron (TFM) under field conditions was evaluated on a pear orchard in Greece. Residues were determined by UV-HPLC analysis, with a detection ... -
Distribution and stability of aflatoxin M-1 during processing, ripening and storage of Telemes cheese
(2001)Telemes cheeses were produced using milk that was artificially-contaminated with aflatoxin M-1 at the levels of 0.050 and 0.100 mug/l. The cheeses produced in the two cheese-making trials were allowed to ripen for 2 months ... -
Distribution and stability of aflatoxin M-1 during production and storage of yoghurt
(2002)Yoghurt from cow's milk artificially contaminated with aflatoxin M-1 (AFM(1)) at levels of 0.050 and 0.100 g l(-1) was fermented to reach pHs 4.0 and 4.6. Yoghurt fermented to pH 4.6 was also used for preparing strained ... -
Effect of harvest time and storage conditions on almond kernel oil and sugar composition
(2003)The effect of storage for 6 months at 5degreesC (80% RH) versus 20degreesC (60% RH) of shelled versus in-shell almonds was studied on early versus late harvested nuts from 'Ferragnes' and 'Texas' trees. Kernel quality ... -
Effect of olive leaf (Olea europea L.) extracts on protein and lipid oxidation in cooked pork meat patties enriched with n-3 fatty acids
