Polyesteramide resin (MAPEAM) was prepared from N,N-bis(2-hydroxy ethyl) Melia azedarach oil fatty amide (HEMAFA) a precursor of natural renewable resource using polycondensation reaction with maleic acid. With the view to improve the physico-mechenical properties aluminium was incorporated in backbone of the polymer to obtain the alumina incorporated polyesteramide resin of Melia azedarach see...

A study was undertaken of the physical and chemical characteristics and insecticide properties of melia (Melia azedarach L.) (Meliaceae) fruit and leaves; melia has been introduced in Chile for ornamental purposes. The physical and chemical properties were evaluated in two stages of fruit and leaf maturity, i.e., green /mature, and mature/juvenile, respectively. Laboratory bioassays were carrie...

OBJECTIVE To investigate the antibacterial potential of the polar and non-polar extracts of the seeds of Melia azedarach (M. azedarach) L. (Meliaceae) against eighteen hospital isolated human pathogenic bacterial strains. METHODS Petrol, benzene, ethyl acetate, methanol, and aqueous extracts at five different concentrations (1, 2, 5, 10 and 15 mg/mL) were evaluated. Disk diffusion method was ...

Macrophomina phaseolina (Tassi) Goid is a soil-borne fungal pathogen that causes root rot disease in more than 500 plant species but no registered fungicide is available for its control. The present study was carried out to investigate the antifungal activity of aqueous leaf extracts of Azadirachta indica A. Juss., Melia azedarach L. and Toona ciliata Roxb. (Meliaceae) against M. phaseolina. Aq...

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) ...

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...
