(Fibre pits in wood of Xylopia emarginata Mart. (Annonaceae), Reserva Biológica e Estação Ecológica de MogiGuaçu, São Paulo State, Brazil). The influence of environmental conditions such as flooding areas on the anatomical features of wood is little known. The aim of this study was to compare the fibre pits in the stems and in the roots of Xylopia emarginata growing in a swampy forest and in a ...

The Brazilian cerrado has undergone an intense process of fragmentation, which leads to an increase in the number of remnants exposed to edge effects and associated changes on environmental conditions that may affect the phenology of plants. This study aimed to verify whether the reproductive phenology of Xylopia aromatica (Lam.) Mart. (Annonaceae) differs under different light conditions in a ...

Xylopia aethiopica A. Rich (X. aethiopica; Annonaceae) is used commonly in Nigeria by traditional herbalists and pastoralists to control gastrointestinal helminth parasites. The anthelmintic effect of the crude methanol extract was evaluated in rats experimentally infected with the rat hookworm Nippostrongylus brasiliensis. Thirtyfi ve rats were each infected subcutaneously with 200 third stage...

The chemical composition of four oil samples of Xylopia aethiopica isolated from trunk bark harvested in three Ivoirian forests was investigated by chromatographic (GC with retention indices) and spectroscopic techniques (MS, 13C NMR). Thirty compounds accounting for 90.2-98.2% of the oil have been identified. X. aethiopica stem bark produced a monoterpene-rich essential oil, whose composition ...

Lecanodiaspis dendrobii Douglas, 1892 (Hemiptera: Coccoidea: Lecanodiaspididae) and the associated parasitoid Cephaleta sp. (Hymenoptera: Pteromalidae) are reported for the first time in Brazil. Specimens of this scale insect were collected on branches and stems of Acacia mangium Willd., Leucaena leucocephala (Lam.) de Wit (Fabaceae), Morus nigra L. (Moraceae), Citrus reticulata Blanco (Rutacea...

Mercerized wood species were impregnated with N, N-dimethylacetamid. The FT-IR showed enhanced absorption at 1419 cm(-C-/CH3), and the 1267 cm (-N-/ CH3) stretching band confirmed the polymerization reaction. Differential scanning calorimetric analysis indicated that the decomposition temperature of polymer-filled wood gives a higher thermal stability compared to the raw material. Polymer-fille...

The rising human population, particularly in the developing countries, and the attendant socioeconomic effects necessitates the need for its effective regulation. This study aims at exploring the contraceptive efficacy of the fruit extract of Xylopia aethiopica (Dunal) A Rich, a plant with wide ethnomedicinal, pharmacological and social values, in combating this public health challenge. Forty e...
