The transmission in West Africa of Schisto&&a haematobium by Bulinus truncatus and B. globosus is well known (BROWN, 1980). On the contrary, B. senegalensis, widely distributed in the sub-desert and sahelian zone and associated principally with a temporary environment (BETTERTON et al., 1983), has been found naturally infected in Senegal and The Gambia only (VERCRUYSSE et al., 1985). In Niger, ...

Background/Aim: The aim of this study was to evaluate the cytotoxic and apoptotic effects of chloroform extract (ASCH) from the seeds of Annona squamosa. Materials and Methods: MTT assay was employed to determine the cytotoxicity of the extract on A-549 and EAC cells and IC50 values were calculated. The apoptotic effects induced by the ASCH was evaluated by Acridine Orange Ethidium Bromide dual...

Annona squamosa seeds extracts showed anthelmintic activity against Haemonchus contortus, the main nematode of sheep and goat in Northeastern Brazil. A compound 1 was isolated from ethyl acetate extract and inhibited the egg hatching of H. contortus at 25 mg ml(-1). The structure of 1 was determined as a C37 trihydroxy adjacent bistetrahydrofuran acetogenin based on spectroscopic analysis.

Methanolic extract of leaves of A. squamosa was tested for mosquitocidal effect against C. quinquefasciatus. A liquid mosquito insecticide formulation was prepared with the extract (1, 3 and 5 %w/w) using deodorized kerosene as solvent and investigated for its knock-down and 24 hr mortality. The extract formulation produced dose dependent activity, exhibited significantly shorter knock down KD5...

Eighteen plant extracts from nine traditional Mexican medicinal plants were tested for antifungal activity against two dermatophyte fungal species (Trichophyton mentagrophytes and Trichophyton rubrum), one non-dermatophyte (Aspergillus niger), and one yeast (Candida albicans). The strongest effect was manifested by the hexane extracts from Eupatorium aschenbornianum and Sedum oxypetalum, as wel...

The aim of this study was to determine the preliminary phytochemical component and antibacterial activity of the leaves extract of Guiera senegalensis lam (Combretaceae) against three clinical isolates (Staphylococcus aureus, E. coli and Klebsiella species) using standard method of analysis. The test for phytochemical component revealed the presence of alkaloid, anthraquinolones, tannin and phl...

Numerous bioactive compounds and phytochemicals have been reported to be present Annona muricata (Soursop). Some of these chemical compounds have been linked to the ethnomedicinal properties of the plant and its antioxidant properties. The aim of this study was to assess the proximate composition, phytochemical constituents and in vitro antioxidant properties of A. muricata using standard bioch...

objective:the purpose of this study was to investigate the effects of piroxicam co-administration with ethanolic stem-bark extract of khaya senegalensis on biomarkers of oxidative stress and gastro-toxicity in wistar rats. materials and methods: thirty healthy male and female albino wistar rats (190-220 g) were grouped into six (n = 5) with designated treatments including: normal saline, piroxi...

The incidence of cancer is increasing each year, which generates concerns regarding the efficacy of the current treatment options. This has caused patients to seek alternatives to complement or to replace surgery, chemotherapy and radiotherapy. Annona muricata and other plants have been shown to have promising compounds that can be utilised in the treatment of cancer. Native to the tropical and...
