Abstract:

The contribution of oxidative stress to the pathogenesis of several health conditions and its association with life-threatening diseases such as malaria has necessitated the search for more phytochemicals with antioxidant properties. Various parts of Raphia hookeri such as the leaves, fruit and sap have been moderately studied and applied in different areas of industry. However, the epicarp is generally discarded. The ethanolic extracts of Raphia hookeri leaf and epicarp were herein investigated for their total phenolic and flavonoid contents using spectrometric methods. 1,1-diphenyl-2-picryl

Purpose: To develop an extended-release formulation of domperidone using a blend of Raphia hookeri gum and hydroxypropyl methylcellulose as tablet matrix.Methods: Tablets (400 mg) containing 30 mg domperidone (DPD) were formulated using binary mixtures of hydroxypropyl methylcellulose (HPMC) and Raphia hookeri gum (RHG) as matrix former; and microcrystalline cellulose (MCC) as direct compression excipient. The proportions of the matrix formers (40 % of tablet weight) was varied as 100:0, 75:25, 50:50, 25:75 and 0:100. The composition of the matrix former was also kept constant (50:50) while MC

The soils pH were moderately to strongly acidic with their values ranging from 4.50 - 4.52. The hydromorphic soils supporting the growth of <em>Raphia hookeri</em> palms contained low concentration of total N, available P and relatively low exchangeable cations, Ca, Mg, K and Na.

Abstract:

Raphia hookeri fruits are used for fishing in Nigeria due to their ichthyotoxic properties. This study investigated the toxic effects of R. hookeri on the reproductive capacity of Clarias gariepinus. The results from both short-term (96-hour test) and long-term (3-month sublethal test) bioassays revealed a linear relationship between R. hookeri extract dose and negative effects on the catfish. The percentage survival of both sexes of the catfish decreased with increasing extract concentration at short-term exposure, with LC50 values of 600 mg/L and 800 mg/L for male and female, respectively.

Abstract:

AbstractThe biology of the aphid, Cerataphis variabilis H.R.L., on Raphia hookeri Mann & Wendl., was studied in the laboratory and the field using a ‘clip-on’ cage and a sleeve cage. The first instar lasted 5.1 days. The second and third instars each lasted 2.45 days, while the fourth instar lasted 2.4 days. The total developmental period of the nymphs was 11.3 days at 26.4 ± 1.43°C and r.h. 83 ± 1.46%; 11.6 days at 26.4 ± 1.63°C and r.h. 85 ± 1.19%; 12.9 days at 27.9 ± 1.04°C and r.h. 75.5 ± 1.64%; 12.95 days at 27.8 ± 0.33°C and r.h. 69 ± 1.23%; 15 days at 21.4 ± 0.58°C and r.h. 45 ± 1.7

Abstract:

Raffia (Raphia hookeri Mann & Wendl.) heart, a little-known vegetable, is usually eaten after cooking in some regions of the Cote dIvoire. The proximate composition of the fresh state and the effect of cooking time (15, 30 and 45 min) on biochemical parameters were investigated. The results show that fresh raffia heart contains nutrients such as proteins (14.53 Â± 0.03 g/100g), lipids (2.60 Â± 0.10 g/100g), total sugars (35.61 Â± 0.13 g/100g) and phytochemicals, in particular total polyphenols (5.86 Â± 0.38 g/100g), flavonoids (0.75 Â± 0.20 g/100g) and tannins (1.93 Â± 0.9 g/100g).

Abstract:

Agroforestry is promoted as a practice at the crossroads of sustainability and productivity objectives; however, many agroforestry programmes have had mixed effects due to a lack of understanding of the compatibility of the species supplied to farmers with cocoa and a failure to take account of their knowledge in designing the programmes. This paper, therefore, examines the effects of socio-economic and agroforestry factors on cocoa yields in Côte d’Ivoire, West Africa. The data used come from surveys of 150 farmers in three areas of the country: Bonon, Soubré and Biankouma. The choice of thes

Abstract:

<em>This study presents a comparative analysis between traditional gins produced from oil palm (Elaeis guineensis) and raffia palm (Raphia hookeri) sap. Physicochemical quantification revealed the raffia palm gin exhibited significantly lower moisture content (27.0%) yet higher total titratable acidity (0.134 g) compared to the oil palm gin (29.7% moisture; 0.014 g acidity). Mineral profiling indicated both gins were below established regulatory limits for toxic metals including lead (0.083 and 0.042 mg/kg) and cadmium (0.038 and 0.028 mg/kg) in oil palm and raffia palm gin respectively.
