Leptadenia reticulata of Asclepidaceae family is a shrub, originally property of Petroleum ether, Alcohol & Chloroform extract of L. reticulata. The antimicrobial testing was carried out by "Disc diffusion method". Amongst the tested three extracts, chloroform extract showed high antimicrobial activity against E. coli, alcoholic extract showed high antibacterial activity against Pseudomonas aer...

BACKGROUND The present study was undertaken to study the larvicidal activity of different extracts of Nerium oleander leaves, and post-treatment temperature- toxicity relationship of these extracts against Culex pipiens. Further, the most potent extract was used to evaluate its biological and genotoxic activities. METHODS Crude extracts of N. oleander leaves were prepared using water, chlorof...

The Anthelmintic activity of petroleum ether, methanol and chloroform extract of rhizomes of Nymphaea rubra Linn were evaluated separately and the activities were compared with that of Albendazole. The petroleum ether, ethanol and chloroform extract exhibited dose dependent activity. The ethanolic extract showed remarkable Anthelmintic activity.

This study evaluated the biological activity of an ether extract and barbatic acid (BAR) from Cladia aggregata on embryos and adult mollusks of Biomphalaria glabrata, cercariae of Schistosoma mansoni and the microcrustacean Artemia salina. The ether extract and BAR were obtained by successive extractions with diethyl ether. The obtained extracts were analyzed using thin-layer chromatography (TL...

Present study was carried out to investigate the anthelmintic potential of petroleum-ether extract of Portulaca oleracea against Pheretima posthuma as a species of earthworm. Various concentrations (25‐100 mg/ml) of petroleum-ether extract were evaluated for anthelmintic activity by recording the time required for paralysis and death of worms. Albendazole was used as standard. Result indicates ...

The residual film toxicity, fumigant toxicity and repellent effect of methanol extract of root bark of Calotropis gigantea (Linn) and its chloroform and petroleum ether (40-60°C) soluble fractions were evaluated against several inster of larvae and adult of Tribolium castaneum. In residual film toxicity, methanol extract and its chloroform and petroleum ether fractions showed insecticidal activ...

Studies of Indigofera tinctoria Linn has shows that it possesses low toxicity. Phytochemical evaluation of leaf extract of Indigofera tinctoria Linn has been carried out to characterize some constituents present therein. Qualitative analysis of the extracts showed the presence of flavonoids, alkaloids, glycosides, terpenoids. Five compounds have been isolated from petroleum ether extract and me...

The present study was conducted to investigate the chemical composition of rice polishing available in Pakistan used in poultry rations as an energy source. Chemical analysis of 195 samples was done. Overall, 60% samples had either lower or higher percentage of ether extract as compared to reference value (1316%). Large number of samples (41.54%) showed lower value of ether extract (less than 1...

This study describes the biological activity of the dried leaves, stem and rhizomes of Curcuma zedoaria belonging to the family Zingiberaceae. The dried powders of the plant were extracted with organic solventsmethanol and pet ether sequentially by the maceration process. The crude extract of methanol and pet ether were then investigated for analgesic and antimicrobial activity. At an oral dose...

background: woodfordia fruticosa is used traditionally as antidysenteric compound for fodder animals. stem and flower extracts are previously flourished for their antibacterial activity. leaves are also equally important, which are preliminary screened for their bioactive components in present study. objective: evaluation of antibacterial activity of leaves of w. fruticosa and detection of thei...
