From the methanol extract of Penicillium sp. cultivated on sterilized rice for three weeks we isolated three new meroterpenes preaustinoid A1, A2 and B1. The fungus was isolated from the root bark of Melia azedarach after surface sterilization. The structures of these compounds were identified by intensive spectroscopic studies.

      The fruit of Melia azedarach L. (Meliaceae) was extracted with hexane, and its fatty acids methyl ester was analyzed using GC/MS. Thirteen components representing 85.1% of the total extract were identified. The major components identified were methyl palmitate (18.8%), methyl linolenate (16.1%) and methyl linoleate (9.8%). The fruits’ extract had a LC50 of 5.5 ppm agai...

Natural products, including plants, animals and minerals have been the basis of treatment of human diseases. Melia azedarach L, commonly known as mahanimba belongs to family Meliaceae. It is large evergreen tree found throughout India and very similar to neem. Traditionally it is used as anthelmintic, antilithic diuretic, astringent and stomachic [1]. Various scientific studies reported the ant...

Plant derivatives possessing insect repellent and antifeedant properties could offer an alternative approach for managing crop pests and dealing with insect-transmitted diseases. This chapter summarizes results from studies on insecticidal effects of Melia azedarach extracts from Central Argentina. Extracts from different plant structures (green/ripe fruits, green/senescent leaves) and a variet...

Methanolic extracts of leaves and seeds from the chinaberry tree, Melia azedarach L. (Meliaceae) was tested against mature and immature mosquito vector Anopheles stephensi Liston (Diptera) under laboratory condition. The extract showed strong larvicidal, pupicidal, adulticidal, antiovipositional activity, repellency and biting deterency. The M. azedarach seed and leaf extracts were used to dete...

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...
