Hibiscus tiliaceus, locally known as Bhola was examined for phytochemical properties and its cytotoxic, antibacterial, analgesic and neuropharmacological activities using the ethanol extract of leaf and bark. The phytochemical analysis of the leaf extract indicated the presence of tannins, whereas bark extract indicated the presence of alkaloid, reducing sugar and tannins. A preliminary cytotox...

The aqueous methanolic extract of the aerial parts of Fagonia arabica L. (family Zygophyllaceae) was successively fractionated using certain organic solvents. From the ethyl acetate fraction, two flavonoid glycosides were isolated and identified as kaempferol-7-O-rhamnoside and acacetin-7-O-rhamnoside. Four triterpenoidal glycosides were isolated from the butanolic layer. Their structures were ...

DHF cases tend to increase from year in Indonesia. So the government makes efforts control of Dengue Fever (DHF) which are usually done chemically and harm environment health. There is a need for safer, more effective, environmentally friendly controls, such as using natural ingredients larvicides. Among having potential larvicide Bintaro leaves (Cerbera manghas). The purpose this study was det...

An attempt is made in the present study to analyse larvicidal activity of Haridra and Tulsi against Aedes Anopheles larvae. Larval bioassays were carried out at different concentrations 50-500ppm. The larval mortality fourth instar larvae A. aegypti after 24h treatment was observed separately control, 50, 62.5, 100, 150, 250, 300 500 ppm concentrations. Based on Probit analysis, Significant eff...

The naturally-derived insecticide spinosad (Conserve SC) was evaluated against larval Culex pipiens L. (Diptera: Culicidae) under laboratory and field conditions in Antalya, Turkey. Laboratory bioassays showed that the 24 h LC50 and LC90 against late 3rd and early 4th instars were estimated at 0.027 and 0.111 parts per million, respectively, while adult emergence was eliminated at concentration...

Fipronil, a relatively new insecticide more recently developed than organophosphates and pyrethroids, has been detected in surface water draining from agricultural and urban-developed areas. This insecticide is primarily lost through subsurface and surface drainage from terrestrial areas where it has been applied. Invasive aquatic plants often need to be managed in these receiving water bodies ...

The effect on aqueous and alcoholic extracts of the leaves of Sencio nudicaulis Buch. Ham. was studied on the spontaneous movements of the whole worm and nerve-muscle preparation of Setaria cervi and on the survival of micro-filariae in vitro. Aqueous as well as alcoholic extracts caused inhibition of spontaneous motility of the whole worm and nerve-muscle preparation of S. cervi characterized ...

The impacts of aqueous extracts from different parts (root, stem, leaf and fruit) of bitter apple Citrullus colocynthis (Cucurbitales: Cucurbitaceae), with five different concentrations, on controlling the bird cherry-oat aphid, Rhopalosiphum padi (L.) (Homoptera: Aphididae) were investigated under laboratory conditions. Results showed that the effects of the aqueous extracts from different par...

The mosquito Aedes aegypti is the vector of the dengue virus, an endemic arbovirus from tropical and subtropical regions of the world. The increasing resistance of mosquitoes to commercial insecticides impairs regular control programs; therefore, chemical prospecting originating from the Amazonian flora is promising for potential new insecticides. Several Piper species are, notably, rich in phe...
