Antioxidant activity of the ethanolic extract of Striga orobanchioides
Journal of Ethnopharmacology, 2003Plants containing flavonoids have been reported to possess strong antioxidant properties. The ethanolic extract of Striga orobanchioides was screened for in vitro and in vivo antioxidant properties using standard procedures. The ethanol extract exhibited IC(50) values of 18.65+/-1.46 and 11.20+/-0.52 micro g/ml, respectively in DPPH and nitric oxide ...

Free Radical Scavenging by Ethanol Extract of Propolis
International Journal of Radiation Biology, 1990The free radical scavenging ability of an ethanolic extract of propolis (EEP) was demonstrated by electron spin resonance spectroscopy, when 2,2-diphenyl-1-picrylhydrazyl (DPPH) was treated with increasing concentrations of EEP. It was shown that the DPPH signal intensity was inversely related to the EEP concentration and to the reaction time.

Korean Journal of Oriental Physiology & Pathology, 2015
Both Portulaca oleracea (PO) and Glechoma hederacea (GH) have been used as traditional medicine due to the multiple pharmacological activities. However, the effects of PO and GH in the pathology of periodontitis is still elusive. In this study, we examined anti-microbial activity of PO ethanol extract (POEE) and GH ethanol extract (GHEE) in vitro, and ...

Chemistry and pharmacology of an ethanol extract of Bumelia sartorum
Journal of Ethnopharmacology, 1985Bumelia sartorum has been mentioned in Brazilian folklore for its reputed use in the treatment of diabetes mellitus and inflammatory disorders. An ethanol extract of root bark elicited a hypoglycemic effect in normal and alloxan-induced diabetic rats. In addition, the extract altered glucose tolerance in alloxan-induced diabetic rats, enhanced glucose ...

Mutagenicity of ethanolic extracts of used acrylic dentures
Mutation Research/Genetic Toxicology, 1994The in vivo physicochemical sorption of mutagenic substances onto acrylic polymers was investigated in worn acrylic dentures. Thus, ethanolic extracts of acrylic dentures from 41 of a total of 69 human donors (60%), were found mutagenic in the standard plate incorporation Salmonella mutagenicity test against either TA98 or TA100 strains.

Estrogenic effects of ethanol and ether extracts of propolis
Journal of Ethnopharmacology, 2002Propolis obtained from honeybee hives has been used in Oriental folk medicine as an anti-inflammatory, anti-carcinogenic, or immunomodulatory agent. The potential estrogenic activity of propolis was investigated in vitro using the MCF-7 human breast cancer cell proliferation, human estrogen receptor (hER) binding and yeast-based steroid receptor ...

Antioxidant activity of ethanolic extracts of amaranth seeds
Nahrung/Food, 2002Antioxidant activity of ethanolic extracts obtained from two amaranth species was evaluated in a beta-carotene-linoleic acid model system. The addition of amaranth extracts in the range of 0.01-0.1% inhibited degradation of a beta-carotene in a model emulsion during incubation at 60 degrees C; 0.05% addition of amaranth seeds extract was proposed as ...

Antimutagenicity mechanisms of the Rhoeo discolor ethanolic extract
Experimental and Toxicologic Pathology, 2011Rhoeo discolor, a medical plant from Mexico, is known to be an antioxidant and chemoprotective antimutagen. Rhoeo discolor ethanolic extract (EERD) is a complex mixture, so in this study its antimutagenic mechanisms were further evaluated.Employing Ames test, with uvrB- and uvrB+ strains, its antimutagenic activity against frameshift mutagens 2-amino ...

The gastroprotective activity of the ethanol extract of Ageratum conyzoides
Journal of Ethnopharmacology, 2003The ethanol extract of Ageratum conyzoides was evaluated for gastroprotection in rats using the Ibuprofen, ethanol and cold restraint stress ulcer models. Efficacy was assessed by determination of mean ulcer size, ulcer number and ulcer index. Oral administration of the ethanol extract at dose levels of 500 and 750 mg/kg significantly protected gastric

Hepatoprotective activity of the ethanol extract of Sarcopyramis Nepalensis
Journal of Huazhong University of Science and Technology [Medical Sciences], 2012The present study examined the protective effect of the ethanol extract of Sarcopyramis nepalensis (EESN) on agents-induced hepatotoxicity in mice and the possible mechanism. Acute liver injury was induced by administration of either CCl(4) or D-GalN. The animals were divided into 5 groups in terms of different treatment: normal group, CCl(4) or D-GalN
