Transverse shrinkage variations within tree stems of Melia azedarach planted in northern Vietnam

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...

Anti-moulting activity in Brazilian Melia azedarach.

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 ...

Quantitative Determination of Azadirachtin in Melia indica and M. azedarach

Background: Melia indica and M. azedarach (Meliaceae) are widely used in traditional medicine. These species are considered as natural pesticides. Their major compound is azadirachtin (AZD) which is considered as the marker for quality control of these species. Objective: In the present investigation, AZD content of the leaves and fruits (comprising the whole fruit, peel, pulp and seeds) of M....

Antiparasitic activity of Melia azedarach growing in Argentina

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.
