Antibacterial activity of phyto-mediated silver nanoparticles developed from Melia azedarach

Potent limonoid insect antifeedant from Melia azedarach.

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...

Green Synthesis of Silver Nanoparticles and Its Effect on Total Proteins in Melia Azedarach Plant

Silver nano-particles have different biological applications due to their compatibility. Chemical methods usually result in remaining some amounts of toxic reactions on the nano-particles. For this reason, the use of plants as sustainable and accessible resources in preparation of compatible nano-particles has attracted a lot of attention in the recent years. This research investigated the gree...

Cytotoxic tirucallane triterpenoids from Melia azedarach fruits.

The phytochemical investigation of the dichloromethane-soluble part of the methanol extract obtained from the fruits of Melia azedarach afforded one new tirucallane-type triterpene, 3-alpha-tigloylmelianol and three known tirucallanes, melianone, 21-beta-acetoxy-melianone, and methyl kulonate. The structure of the isolated compounds was mainly determined by 1D and 2D NMR experiments as well as ...

Preparation and Antibacterial Activity of Silver Nanoparticles

Uniform silver nanoparticles have been prepared through the chemical reduction of silver ions by ethanol in presence of sodium linoleate. TEM micrograph shows a uniform distribution of the particles with an average size of 12 nm. Further, the antimicrobial activity of silver nanoparticles shows that these nanoparticles can be used as effective growth inhibitors against Staphylococcus Basillus, ...
