background & aim: homalium letestui pellegr (flacourtiaceae) used traditionally by the ibibios of southern nigeria to treat stomach ulcer, malaria and other inflammatory diseases was evaluated for antiulcer properties.  experimental: the effects of ethanol stem extract of h. letestui (200 – 600 mg/kg) and fractions (aqueous and dichloromethane, 400 mg/kg) on experimentally induced ulcer wer...

The effects of iron oxides and organic matter on the partitioning and chemical lability of U and Ni were examined for contaminated riparian sediments from the U.S. Department of Energy's Savannah River Site. In sequential extractions of four sediments that ranged from 12.7 to 82.2 g kg(-1) in organic carbon, U was found almost exclusively in moderately labile fractions (93% in acid-soluble + or...

BACKGROUND AND OBJECTIVE Bronchiolitis obliterans (BO) has been reported to develop following ingestion of Sauropus androgynus (SA), a leafy shrub distributed in Southeast Asia. Little is known about direct effects of SA on airway resident cells or haematopoietic cells in vitro. Identification of the SA component responsible for the development of BO would be an important key to elucidate its m...

Ferulago species have been utilized since ancient times as digestive, sedative, aphrodisiac, along with in salads or as a spice due to their special odors. The study reports isolation and characterization of bioactive compounds of Ferulago pachyloba (F. pachyloba), Ferulago trachycarpa (F. trachycarpa), Ferulago bracteata (F. bracteata), and Feru...

in the present work, the bioassay screening of the essential oil and various extracts of two plants including fruits of heracleum persicum desf. and rhizomes of zingiber officinale rosc. have been studied with brine shrimp test. there is only one report about cytotoxicity of h. sphondylium in literature and so h. persicum has been used as second selection. at first essentials oil and various ex...

background and objectives: resistance towards reveling antibiotics has captured great interest in evaluating the antimicrobial properties of the natural plants. taraxacum mongolicum is widely used as a folklore medicinal plant for its diuretic, antirheumatic and anti-inflammatory properties. though there are some reports on antimicrobial properties of taraxacum mongolicum, studies on antibacter...

Peptic ulcer disease has remained a global threat due to several complications such as perforation, gastrointestinal obstruction and organ penetration associated with the disease. This study evaluated phytochemical composition anti-ulcer activity of crude extract fractions Acanthus montanus on an indomethacin-induced in mouse model. The plant was extracted using cold maceration methanol fractio...

The fractions of different polarity, namely chloroform, ethylacetate, n-butanol, and remaining water fractions, were fractionated from an aqueous extract of V. vinifera leaves. The antibacterial, antifungal, antiviral, antioxidant activities, and total phenolic content of these fractions were investigated. The chloroform fraction showed a promising effect against Herpes simplex virus type-1 (HS...

Objective. The whole plant of Houttuynia cordata has been reported to have potent antihyperglycemic activity. Therefore, the present study was undertaken to investigate the glucose utilization capacity of bioactive fractions of ethanol extract of Houttuynia cordata (HC) in isolated rat hemidiaphragm. Methods. All the fractions, that is, aqueous (AQ), hexane (HEX), chloroform (CHL), and ethyl ac...

The crude ethanolic extract and n-hexane, dichloromethane, ethyl acetate, n-butanol and aqueous fractions of Dodonaea viscosa were analyzed for antibacterial potential against four Gram positive bacteria: Bacillus subtilis, Bacillus cereus, Micrococcus luteus, Staphylococcus aureus, and three Gram negative bacteria: Escherichia coli, Salmonella typhi, Pseudomonas aeruginosa. Preliminary screeni...
