Investigation into antimalaria activity of various fractions of Morinda lucida leaf extract and Alstonia boonei stem bark was conducted using standard techniques. The present study confirms the antimalarial activity of Morinda lucida and Alstonia boonei. Morinda lucida exhibited MIC of 0.6mg/ml and Alstonia boonei MIC 0.2mg/ml. The anti plasmodia activity of both plants were found to reside maj...

The aim of this work was to formulate Alstonia boonei dried stem bark powder into tablets by wet granulation method using acacia, gelatine and sodium carboxymethyl cellulose as binders at concentrations of 1, 2, 4 and 8% w/w. The phytochemistry of the stem bark of Alstonia boonei was evaluated. The micromeritic properties of the granules prepared were studied. The tablets were evaluated using t...

Malatreat is marketed by Paxherbals as a multi-component antimalarial preparation made from Alstonia boonei, Sida acuta and Tridax procumbens. Phytochemical screening of hexane and ethanol extracts obtained by infusion revealed the presence of alkaloids, saponins, tannins, anthraquinones, steroids, flavonoids, phlobatannins, glycosides and cardiac glycosides. These secondary metabolites are als...

Methods Haemozoin was extracted from blood samples of all the malaria positive patients studied by centrifugation, and the concentration was analyzed spectrophotometrically at 400nm wavelength. Comparative anti-malaria activity of some conventional antimalarials, including Maldox, Halfan, Artecxin, Amatem, Mefloquine (quinolines) and Malmed, as well as the leaf and stem back extracts of some lo...

Species that are not yet barking were wounded conducting experimental debarking. The wound was rectangular with 30 cm vertically lateral extent 10 cm. Every three m...

Experiments were conducted to study the effectiveness of powders of some underutilized botanicals for the control of Sitophilus zeamais. The tested plants are: Piptadeniastrum africanum, Piper guineense, Alstonia boonei, Garcinia kola, Xylopia aethiopica, Picralima nitida and Aristolochia repens. The effects of the powders were observed at different dosage rates : 0.0g (Control), 0.5g, 1.0g, 1....

The bioactivity of Alstonia boonei De Wild leaf alkaloid was tested under laboratory bioassay against the legume pod borer, Maruca vitrata Fabricius. The alkaloid was incorporated into standard M. vitrata artificial diet at five doses [0.00 % (Control), 0.02 %, 0.05 %, 0.10 % and 0.20 %], and fed to the newly emerged first instar M. vitrata larvae in plastic wells under laboratory conditions.
