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 against the larvae of anophles...

The impact of three different doses of botanical insecticide derived from the syringa tree, Melia azedarach and the neem tree, Azadirachta indica was tested on the behaviour of the diamondback moth, Plutella xylostella (Linnaeus). Both botanical insecticides had a significant impact on larval behaviour. At higher doses the extracts showed feeding deterrent activity, with larvae preferring the u...

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...

AKT/GSK-3β/β-catenin signaling pathway plays an important role in the progression of colorectal cancer (CRC). Toosendanin (TSN) is a triterpenoid extracted from the bark or fruits of Melia toosendan Sieb et Zucc and possesses antitumour effects on various human cancer cells. However, its effect on CRC remains poorly understood. The present study investigated the effect of TSN on CRC SW480 cells...

Indigenous plant use-systems have evolved under, and constantly adapted to human and non-human impacts. In the last decades however, increasing socioeconomic and cultural transformations, including land-use change, outmigration, globalized markets, the introduction of new species, and climate change have led to a decreasing availability of indigenous resources, and are ultimately leading to a r...

The seed oil of Azadirachta indica A. Juss (neem) is used in traditional medicine for its antidiabetic, spermicidal, antifertility, antibacterial, and wound healing properties. The present study was undertaken to investigate the quantitative aspects of follicular development in cyclic female albino rats (135 +/- 10 g; 8 groups with 6 animals in each group) after oral administration of polar (PF...

In the present study, aqueous extract of eight plants, namely Azadirachta indica A. Juss, Melia azedarach Linn., Lantana camara L. Moldenke., Cannabis sativa Linn., Nerium indicum Mill., Eucalyptus sp., Ricinus communis Linn. and Solanum nigrum Linn. were tested for antifeedant and toxic effects against Pieris brassicae (Linn.). The ethanol extract of four potential plants were further tested f...
