| concentrations of heavy metals and plant nutrients in water, sediments and aquatic macrophytes of anthropogenic lakes (former open cut brown coal mines) differing in stage of acidification. | concentration of heavy metals (al, ba, cd, co, cr, cu, fe, mn, ni, pb, sr, v and zn) as well as macronutrients (n, p, k, ca, mg, s) were measured in water, bottom sediments and plants from anthropogenic lakes in west poland. the collected plants were: phragmites australis, potamogeton natans, iris pseudoacorus, juncus effusus, drepanocladus aduncus, juncus bulbosus, phalaris arundinacea, carex remota and calamagrostis epigeios. two reference lakes were sampled for nymphaea alba, phragmites austr ... | 2001 | 11778963 |
| a rapid densitometric method for simultaneous quantification of gallic acid and ellagic acid in herbal raw materials using hptlc. | gallic acid and ellagic acid are two widely occurring phenolic compounds of plant origin, to which many biological activities including anticancer and antiviral activity have been attributed. a simple hptlc method has been developed for the simultaneous quantification of gallic acid and ellagic acid. the method was validated for precision, repeatability, and accuracy. instrumental precision was found to be 0.083 and 0.78, and the repeatability of the method was found to be 1.07 and 1.50 (% cv) f ... | 2005 | 15881089 |
| in vitro antibacterial and antitumor activities of some medicinal plant extracts, growing in turkey. | to investigate antibacterial and antitumor activities of 51 different extracts prepared with 3 types of solvents (water, ethanol and methanol) of 16 different plant species (ajuga reptans (a. reptans) l., phlomis pungens (p. pungens) willd., marrubium astracanicum (m. astracanicum) jacq., nepeta nuda (n. nuda) l., stachys annua (s. annua) l., genista lydia (g. lydia) boiss., nuphar lutea (n. lutea) l., nymphaea alba (n. alba) l., vinca minor (v. minor) l., stellaria media (s. media) l., capsella ... | 2013 | 23790332 |
| anxiolytic activity of nymphaea alba linn. in mice as experimental models of anxiety. | the aim of the present work was to evaluate the anxiolytic effect of an ethanolic extract of nymphaea alba linn. in mice. | 2011 | 21455422 |
| inhibition of potassium bromate-induced renal oxidative stress and hyperproliferative response by nymphaea alba in wistar rats. | kbro3-mediated renal injury and hyperproliferative response in wistar rats. in this communication, we report the efficacy of nymphaea alba on kbro3 (125 mg/kg body weight, intraperitoneally) caused reduction in renal glutathione content, renal antioxidant enzymes and phase-ii metabolising enzymes with enhancement in xanthine oxidase, lipid peroxidation, gamma-glutamyl transpeptidase and hydrogen peroxide (h202). it also induced blood urea nitrogen, serum creatinine and tumor promotion markers, v ... | 2005 | 16119199 |
| anticarcinogenic effect of nymphaea alba against oxidative damage, hyperproliferative response and renal carcinogenesis in wistar rats. | the present study investigates the prophylactic effect of nymphaea alba against ferric nitrilotriacetate (fe-nta)-induced renal oxidative stress, hyperproliferative response and renal carcinogenesis in wistar rats. treatment with fe-nta (9 mg fe/kg body weight, intraperitoneally) enhanced iron-ascorbate-induced renal lipid peroxidation, xanthine oxidase, gamma-glutamyl transpeptidase and hydrogen peroxide (h2o2) generation with reduction in renal glutathione content, antioxidant enzymes, viz., g ... | 2005 | 15881650 |
| expression pattern of inner no outer homologue in nymphaea (water lily family, nymphaeaceae). | two homologues of inner no outer ( ino) in nymphaea alba and n. colorata (nymphaeaceae) were isolated and the expression pattern of the n. alba ino homologue naino was examined by in situ hybridization. the ino homologues obtained have a portion similar to ino in the predicted amino acid sequences between the conserved zinc finger-like and yabby domains. in an in situ hybridization analysis, naino is expressed in the outer epidermis of the outer integument, inner integument, and the tip of the n ... | 2003 | 12928899 |
| heavy metals in three lakes in west poland. | concentrations of heavy metals (ni, cr, co, zn, mn, pb, cd, cu, hg, fe) as well as macronutrients (p, ca, mg) were measured in water, bottom sediments, and plants of three lakes in west poland (southwest of poznan). the plants collected were nymphaea alba, nuphar luteum, ceratophyllum demersum, phragmites communis, typha latifolia, and schoenoplectus lacustris. these plants contained elevated levels of co, zn, pb, cd, cr, and hg. analyses of water and bottom sediments indicated that the lakes we ... | 1999 | 10330316 |
| discovery of new angiotensin converting enzyme (ace) inhibitors from medicinal plants to treat hypertension using an in vitro assay. | angiotensin converting enzyme (ace) inhibitors plays a critical role in treating hypertension. the purpose of the present investigation was to evaluate ace inhibition activity of 50 iranian medicinal plants using an in vitro assay. | 2013 | 24359711 |
| phenolic content of daylight-exposed and shaded floating leaves of water lilies (nymphaeaceae) in relation to infection by fungi. | under suboptimal growing conditions (e.g. a lack of sunshine), floating leaves of nymphaea alba and nuphar lutea can become heavily infected with the fungi colletotrichum nymphaeae and pythium f, respectively. these fungi normally act as decomposers of senescent leaves. mature leaves of nymphaea alba and nuphar lutea contain high concentrations of phenolics, secondary substances known for their fungistatic properties. the production of these compounds requires energy and primary metabolites. the ... | 1997 | 28307624 |
