| nutritional and antioxidant properties of wild edible plants and their use as potential ingredients in the modern diet. | thirteen species of wild edible plants belonging to 11 botanical families consumed in the traditional mediterranean diet were evaluated. sanguisorba minor, quercus ballota and sedum sediforme showed the highest hydrophilic total antioxidant activity (h-taa) and total phenols. asparagus acutifolius, allium ampeloprasum, foeniculum vulgare and malva sylvestris presented high levels of potassium, malva and asparagus are interesting due to their zinc content, and urtica urens contains a high content ... | 2013 | 23944868 |
| evaluation of antinociceptive, antinflammatory activities and phytochemical analysis of aerial parts of urtica urens l. | the antinociceptive and antiinflammatory activities of the ethanol extract of the aerial part of urtica urens were determined by experimental animal models. u. urens extract was found to possess significant antinociceptive activity in chemically induced mouse pain models (ed₅₀ 39.3 mg/kg: 17.2-74.5 mg/kg) in the writhing test and 62.8% inhibition of the licking time in the late phase of the formalin test at a dose of 500 mg/kg p.o. and antiinflammatory activity on carrageenan-induced rat hind pa ... | 2010 | 20564509 |
| drug interaction potential of the seed extract of urtica urens l. (dwarf nettle). | dwarf nettle (urtica urens) seed extract was examined in vivo in the rat for its potential to modulate drug metabolizing enzymes including aminopyrine n-demethylase (apnd; cyp2c6), aniline 4-hydroxylase (a4h; cyp2e1), nitrosodimethylamine n-demethylase (ndma-nd; cyp2e1) erythromycin n-demethylase (ernd; cyp3a1) cyp2d1/2 and glutathione s-transferase (gst). rt-pcr data and western blotting studies clearly demonstrated that cyp2c6 and cyp2e1 mrna levels were substantially increased after urtica tr ... | 2009 | 19441062 |
| in vivo effects of urtica urens (dwarf nettle) on the expression of cyp1a in control and 3-methylcholanthrene-exposed rats. | the in vivo effects of the intraperitoneal administration of an urtica urens l. (dwarf nettle) seed extract were examined on the hepatic, pulmonary, and renal cytochrome p450-dependent monooxygenase activities of rats co-administered with 3-methylcholanthrene (mc). urtica extract was administered by intraperitoneal injection to male wistar rats at 200 mgkg(-1)day(-1) for 4 days from which were also co-administered with intraperitoneal injection of 50mg of mc kg(-1) of body weight twice on days 1 ... | 2008 | 18098063 |
| insecticides and arable weeds: effects on germination and seedling growth. | the decline of many arable weed species in northern europe has been attributed to the intensification of modern agriculture and in particular, increasing pesticide use. in this study, we examined the effect of two insecticides, dimethoate and deltamethrin, on the germination and seedling growth of six arable weed species. although germination was unaffected by insecticide application, seedling growth of four species was decreased by exposure to deltamethrin (capsella bursa-pastoris and poa annua ... | 2005 | 16385742 |
| effects of the antirheumatic remedy hox alpha--a new stinging nettle leaf extract--on matrix metalloproteinases in human chondrocytes in vitro. | inflammatory joint diseases are characterized by enhanced extracellular matrix degradation which is predominantly mediated by cytokine-stimulated upregulation of matrix metalloproteinase (mmp) expression. besides tumour necrosis factor-alpha (tnf-alpha), interleukin-1beta (il-1beta) produced by articular chondrocytes and synovial macrophages, is the most important cytokine stimulating mmp expression under inflammatory conditions. blockade of these two cytokines and their downstream effectors are ... | 2002 | 11962753 |
