Melia azedarach L. extracts and their activity on Musca domestica L. (Diptera: Muscidae)

RESUMO: "Extratos de Os bioensaios mostraram inibição no desenvolvimento pós-embrionário das moscas e um signifi cativo aumento do período larva recém eclodida-adulto. Além disso, o peso pupal foi reduzido e a proporção sexual alterada. Foi observada toxicidade para os ovos das moscas. Unitermos: Extratos de planta, Diptera, Melia azedarach, regulação do desenvolvimento, atividade biológica. ABSTRACT: Crudes extracts and fractions from seeds of Melia azedarach L. (Meliaceae) have been assayed on Musca domestica Linnaeus, 1758 (Diptera: Muscidae). Thus, the postembryonic development of the fl ies was reduced and the delay from newly hatched larvae to adults had signifi cant increase. In addition, the pupal weights were reduced and the sexual ratio altered. Toxicity to fl y eggs was also observed

Analysis of a Brazilian green propolis from Baccharis dracunculifolia by HPLC-APCI-MS and GC-MS

Ethanol and dichloromethane extracts of a Brazilian green propolis from Baccharis dracunculifolia were analyzed by HPLC-APCI-MS and GC-MS, respectively. The HPLC-APCI-MS technique, at the positive mode, furnished a complete and unequivocal chemical composition of the green propolis sample. It serves as fingerprint for different propolis samples. The composition of the ethanol extract consisted mainly of cinnamic acid and derivatives, flavonoids, benzoic acid and a few benzoates, non-hydroxylated aromatics, and aliphatic acids and esters, which are normally not reported in the literature because they do not absorb UV light. The main constituents of the dichloromethane extract were prenylated compounds, alkanes and terpenoids

Other medicinal plants and botanical products from the first edition of the Brazilian Official Pharmacopoeia

In a previous work, we described the list of medicinal plants and botanical products present in the four editions of the Brazilian Official Pharmacopoeia (FBRAS). The work also discussed the replacement of native Brazilian plants by imported products and synthetics over the last decades. In this paper, we present new data concerning medicinal plants and botanical products present in the first Edition of the FBRAS an in its two supplements
