   • Selon Somasundaram G (2017)

     Extrait Male Wistar albino rats overdosed with paracetamol showed liver damage as specified by increased serum levels of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, total bilrubin & decreased activities of total protein compared with the control group. The aim of the study is to investigate the hepatoprotective activity against paracetamol induced liver damage in rats.

   • Selon Koffuor GA (2012)

     Extrait Animals were grouped & treated with diclofenac, Chlorpheniramine, & Granisetron (reference anti-inflammatory agents), or aqueous & ethanolic extracts of P stratiotes at doses of 30, 100,& 300 mg/kg orally. The aim of the study was to investigate the anti-inflammatory property and possible mechanism of action of aqueous & ethanolic leaf extracts of P stratiotes & to ascertain its safety for use.

   • Selon Tyagi T (2016)

     Extrait Anticancer, Anti-inflammatory, Antimicrobial, Diuretic, Hepatoprotective, Antiarthritic, Antiasthma, Antioxidant, Hypocholesterolemic, Nématicide, Pesticide, Lubricant, Antiandrogenic, Flavor, Hemolytic, 5-Alpha reductase inhibitor, Insectifuge, Antihistaminic, Anti-eczemic, Anti-acne, Anti-coronary, Antifouling effects so that they can be recommended as a plant of phytopharmaceutical importance. The aim to study the phytochemical screening from Pistia stratiotes & Eichhornia crassipes analysis of components present in it by gas chromatography-mass spectrometry (GC-MS).

   • Selon Kyei S (2012)

     Extrait Despite the numerous studies conducted on the anti-inflammatory effect of Pistia stratiotes, its traditional use in the treatment of conjunctivitis & iritis has not been Scientifically evaluated. Results: A rise in body temperature after lipopolysaccharide inoculation was found to be associated with corresponding high erythrocyte sédimentation rate & elevated C-reactive protein levels.

   • Selon Kumar HK (2011)

     Extrait This study was intended to evaluate the analgesic, anti-inflammatory and antipyretic activity of Pistia stratiotes in experimental standard models i.e. The results showed that the ethanolic extract significantly reduce the edema induced by carrageenan within 1 to 3 hrs post dosing & Cotton-pellet induced granuloma models than the petroleum ether extract at all the dose levels used.

   • Selon Somasundaram G (2017)

     Extrait The aim of the study is to investigate the hepatoprotective activity against paracetamol induced liver damage in rats. The effect produced by the leaf extract of Pistia stratiotes was comparable with that of silymarin.

   • Selon Tyagi T (2016)

     Extrait The aim to study the phytochemical screening from Pistia stratiotes & Eichhornia crassipes analysis of components present in it by gas chromatography-mass spectrometry (GC-MS). Therefore ethanol extract of Pistia stratiotes & E.

   • Selon Koffuor GA (2012)

     Extrait Pistia stratiotes is used extensively in inflammatory disorders in several countries including Ghana. Animals were grouped & treated with diclofenac, Chlorpheniramine, & Granisetron (reference anti-inflammatory agents), or aqueous & ethanolic extracts of P stratiotes at doses of 30, 100,& 300 mg/kg orally.

   • Selon Auteur (2009)

     Extrait The antibacterial activity of ethanolic leaf extract of Pista stratiotes against Streptococcus species, Escherichia coli, Staphylococcus aureus & Klebsiella pneumoniae was studied by the agar diffusion & broth dilution methods. Streptococcus species was the most sensitive to the plant material while E coli was the most resistant.

   • Selon Khan M (2011)

     Extrait subtilis, Staphylococcus aureus, gram negative Escherichia coli, Salmonella typhi, Proteus mirabilis & yeast Candida albicans & Rhodotorula rubra, which were comparable with standard antimicrobial drugs tetracycline, vancomicin & nystatin. In phytochemical screening of the ethanolic extract of Pistia stratiote’s aerial part anthraquinone glycosides, cardiac glycosides, cyanogenetic glycosides, flavonoids, steroids, tannins, carbohydrates were found to be present.

   • Selon SARAVANAKUMAR K (2011)

     Extrait The present study was undertaken to determine the antiulcer activity of the ethanol extract from the leaves of Pistia stratiotes.

   • Selon OLUBUKOLA J O (2011)

     Extrait Methodology : Crude extracts of fresh leaves of Ocimum gratissimum, Psidium guajava, Vernonia amygdalina, Kigelia africana, Azadirachta indica, Pistia stratiotes, Euphorbia hirta, bulb of Allium sativum & Zingiber officinale & Curcuma longa, were evaluated using the agar diffusion assay method and minimal inhibitory concentration (MIC) to determine the antibacterial activities against Vibrio Cholerae, Escherichia Coli & salmonella Sp. Was not inhibited by ethanolic extracts of Euphorbia hirta and Curcuma longa, both water and ethanolic extracts of others inhibited the growth of Vibrio Cholerae, Escherichia coli and salmonella Sp to varying degree.

   • Selon Tyagi T (2016)

     Extrait The aim to study the phytochemical screening from Pistia stratiotes & Eichhornia crassipes analysis of components present in it by gas chromatography-mass spectrometry (GC-MS). Therefore ethanol extract of Pistia stratiotes & E.
