Two new phragmalin-type limonoids, Carapanosins A and B (1 and 2), and a new gedunin-type limonoid, Carapansin C (3), together with five known limonoids (4-8) were isolated from the oil of Carapa guianensis AUBLET (Meliaceae) seeds, a traditional medicine in Brazil and Latin American countries. Their structures were elucidated on the basis of spectroscopic analyses using 1D and 2D NMR technique...

The in vitro toxicity of neem seed oil (Azadirachta indica A. Juss, family: Meliaceae, Dogon yaro in Hausa language in Nigeria) was tested against the larvae of a one-host tick, Boophilus decoloratus (family: Ixodidae or hard tick, commonly known as blue tick) parasitic mainly to cattle generally found in savannas of tropical equatorial Africa. The 20, 40, 60, 80 and 100% concentrations of neem...

A fungus, isolated from the root bark of Melia azedarach (Meliaceae), from which a series of meroterpenes have been reported, was identified as Penicillium brasilianum based on analysis of the ITS region of ribosomal DNA. From a rice culture of this fungus, the known phenylpropanoid amides brasiliamide A and B were obtained together with and a new, slightly modified congener, along with the mer...

Six mexicanolide limonoids isolated from the dichloromethane extract of the fruits of Cipadessa fruticosa Blume (Meliaceae) were evaluated against Spodoptera frugiperda (J. E. Smith). Gedunin was used as a positive control. When incorporated into an artificial diet of neonates at 50.0 mg kg(-1), febrifugin A showed 73.3% mortality. All the compounds showed moderate insecticidal activity, except...

Since 2004, an undescribed species of Unaspis (Hemiptera: Diaspididae) has become a damaging pest on Lansium domesticum Corrêa in the Philippines. Its attack on the leaves causes premature senescence and defoliation, resulting in the production of few, underdeveloped, sour fruit and sometimes killing the trees. The scale was misidentified initially as Lepidosaphes ulmi (Linnaeus) and then as Un...

The plants of Meliaceae are native to tropical and subtropical regions as the Americas, west India, Southeast Asia, Southern China. Many species genera Khaya, Swietenia, Aphanamixis, Melia in this family known medicinal have biological activities such antiviral, antimicrobial, antifeeding, insecticidal, cytotoxic properties. objectives research characterize evaluate bioactive limonoids from sev...
