The antiparasitic activity of the drupe extracts of Melia azedarach L. (Meliaceae) growing in Argentina was tested against a tapeworm and an earthworm, showing to be better against tapeworms than the standard piperazine phosphate, which is used in the treatment of Cestoda infections.

Due to the depletion of petroleum oil reserves and the environmental issues both, efforts have made to utilize the renewable resources in the polymer synthesis now-a-days. Among the different renewable resources seed oils of different plants pay considerable attraction due to its unique properties. Melia azedarach is a medium sized tree largely cultivated throughout the country as a shadow tree...

Melia azedarach L. extracts were studied in comparison with selected biorational insecticides against the citrus leafminer Phyllocnistis citrella Stainton under field conditions. Citrus limon (L.) Burm. F. trees were exposed to: Melia extracts of green and mature fruits, Neem oil (30% a.i.), abamectin (1.8% a.i.) and control. Two sprays of each treatment (except for Melia mature fruit extract) ...

A biological invasion of non-native plants is spreading into our natural areas and rights-of way. In the present work, Melia azedarach (Meliaceae) known for its high allelopathic potential is used to investigate its biopesticide capacity on the common model used in bioassays: Raphanus sativus (R. sativus). Exposure of R. sativus to M. azedarach (aqueous/ethanolic) leaves extracts result on toxi...

Systematic fractionation of a fruit extract from Argentine Melia azedarach L., which was monitored by an insect antifeedant bioassay, led to the isolation of meliartenin, a limonoid antifeedant, which existed as a mixture of two interchangeable isomers. At 4 microg/cm2 and 1 microg/cm2, the isomeric mixture was as active as azadirachtin in strongly inhibiting the larval feeding of Epilachna pae...

The larvicidal activities to determine the efficacies of acetone, ethyl acetate, chloroform and butanol dried leaf extracts of Annona squamosa, Cynodon dactylon, Melia azedarach and root extract of Hemidesmus indicus tested against 3 instar Culex quinquefasciatus and Aedes aegypti. The highest larvae mortality was found in the acetone followed by ethyl acetate, chloroform and butanol extract of...

BACKGROUND The increasing use of nanoparticles and nanocomposite in pharmaceutical and processed food industry have increased the demand for nontoxic and inert metallic nanostructures. Chemical and physical method of synthesis of nanostructures is most popular in industrial production, despite the fact that these methods are labor intensive and/or generate toxic effluents. There has been an inc...
