The antibacterial activity of Citrus karna fruit peel extracts was evaluated on bacteria strains like Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Bacillus subtilis. Hexane, chloroform and methanol were used for extraction and the antibacterial activity was performed by agar well diffusion method. The results were compared with ampicillin, a commercial antibacterial agent...

effect of otostegia persica on naloxone-induced morphine withdrawal syndrome was studied in male mice. dependence was induced using daily subcutaneous injections of morphine for three days. morphine was injected to mice at doses of 30 and 45mg/kg on day 1 and 60 and 90mg/kg on day 2 (8:00 am and 6:00 pm). on day 3, morphine (90mg/kg) was injected 1h before oral administration and 1.5h before in...

background : within the framework to control mosquitoes, ovicidal, larvicidal and pupicidal activity of annona senegalensis leaf extract and its 4 fractions against anopheles gambiae and culex quinquefasciatus were evaluated in the laboratory conditions. methods : ovicidal test was performed by submitting at least 100 eggs of mosquitoes to 125, 250, 500, 1000 and 2000 ppm concentrations, while ...

Background: Polygonum bistorta has been used as a remedy for jaundice, smallpox, pimples, measles, cholera, diarrhoea, dysentery, expelling worms, insect stings and snakebites. In this study, the crude extract from P. bistorta and two fractions viz. hexane and chloroform obtained from the crude extract were studied for their median lethal dosages (LD50) in Swiss albino mice. Methods: Powdered ...

Objectives: The present study was to study the phytochemical and antibacterial properties of Alternanthera brasiliana leaf extracts using three different solvents (hexane, chloroform and methanol) against human pathogenic microorganism. Methods: Preliminary phytochemical screening of leaf extracts (in different solvents) of A. brasiliana were qualitatively tested using standard procedures. Thin...

Ficus congensis (Moraceae) is used traditionally in the treatment of various diseases including infectious diseases, infertility, and gastrointestinal disorders. Investigation of hexane extract of the stem bark using chromatographic techniques led to isolation of a xanthone, 1-hydroxy-3,7,8-trimethoxyxanthone (Decussatin). The compound was elucidated based on spectroscopic methods such as nucle...

Hexane, chloroform and ethyl acetate crude extracts of Atalantia monophylla leaf were studied for ovicidal activity against Helicoverpa armigera at 0.5. 1.0, 2.5 and 5.0% concentrations. The ovicidal activity of 67.10% was statistically significant noticed in hexane extract at 5.0% concentration. The least LC50 value of 2.60% was observed in hexane extract with significant Chi-square value at P...

This study was undertaken to evaluate the antioxidant and acetylcholinesterase inhibition properties of stems and leaves of hexane and methanolic extracts of Pluchea indica. Methanolic extract of leaves showed the highest antioxidant activity (IC50= 24.45 ± 0.34 μg/ml) and total phenolic contents (573.52 ± 6.2 mg GAE/100 g crude extract), in DPPH radical scavenging and Folin-Ciocalteu assays re...

background cancer is one of the leading causes of human death. the discovery of new generations of low-cost anticancer drugs with high efficacy and low toxicity is necessary, and is only possible by screening medicinal plants with prior knowledge. objectives in this study, the bioactivities of three medicinal plants from india, including alstonia scholaris, alstonia venenata, and moringa oleife...
