Variation in intrinsic wood properties of Melia azedarach L. planted in northern Vietnam

Study on the extraction process and seasonal variation of Toosendanin in Chinaberry (Melia azedarach L.)

Toosendanin as one kind of plant pesticide exists in the fruits, barks, and leaves of Melia azedarach L. (chinaberry tree). To obtain toosendanin, the sample was defatted with petroleum ether, extracted with ethanol; then the solution was concentrated, and extracted with ethyl acetate. Uniform design and regression analysis were employed to establish a model of extraction and optimize the proce...

An antiviral meliacarpin from leaves of Melia azedarach L.

Bioassay guided purification of the ethyl acetate extract of leaves of Melia azedarach led to the isolation of the limonoid 1-cinnamoyl-3,11-dihydroxymeliacarpin, which showed IC50 values of 6 microM and 20 microM for vesicular stomatitis (VSV) and herpes simplex (HSV-1) viruses, respectively. Its structure was established by spectroscopic methods.

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.

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....
