  • Decoction of Cocos nucifera husk fibre is used indigenously in Nigeria for malaria treatment. Polyphenols have been identified as the phytochemicals responsible for the antimalarial activity of Cocos nucifera husk fibre, though their toxicity has not been evaluated. The polyphenols of Cocos nucifera husk fibre were therefore evaluated for their effects on selected kidney function indices in mice. Fifty mice were randomly divided into five groups (A-E) of ten mice each. Mice in group A were orally administered 5% DMSO solution while those in groups B, C, D and E were orally administered 31.25, 62.5, 125 and 250 mg/Kg body weight of the polyphenols respectively for seven days. Serum urea, creatinine and uric acid concentrations were determined. Serum levels of sodium, potassium, chloride and calcium ions and kidney alkaline phosphatase (ALP), glutamate dehydrogenase (GDH) and gamma-glutamyltransferase (GGT) activities were also determined. The results showed that the polyphenols significantly reduced (p<0.05) urea concentration at 250 mg/Kg body weight and creatinine concentration at all doses compared to controls. The polyphenols caused no significant alteration (p>0.05) in serum uric acid concentration and kidney ALP, GGT and GDH activities compared to controls. There was significant increase (p<0.05) in serum sodium ion concentration at 31.25, 125 and 250 mg/Kg body weight of polyphenols whereas significant increase (p<0.05) in serum potassium and chloride ions was observed at 62.5 and 250 mg/Kg body weight compared to controls. Thus, polyphenols of Cocos nucifera husk fibre may adversely affect some osmoregulatory functions of the kidney, especially at higher concentrations.

  • Cocos nucifera (C. nucifera) oil is indigenously used to treat cardiovascular diseases. However, coconut husk fibre (which is rich in polyphenols) has not been screened for this property. Based on the ethnomedicinal use of polyphenols in treating cardiovascular diseases, this study was carried out to evaluate the effects of polyphenols of C. nucifera husk fibre on selected cardiovascular disease indices in mice. Fifty adult male Swiss albino mice were assigned randomly into five groups (A-E). Mice in groups B, C, D and E were administered 31.25, 62.5, 125, and 250 mg/kg body weight polyphenols of ethyl acetate extract of C. nucifera husk fibre respectively while the control group (A) mice received 5% DMSO for seven days. The mice were sacrificed twenty four hours after the last administration of polyphenols. Heart and plasma lactate dehydrogenase (LDH), alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) activities and plasma lipid profile were determined. Results revealed significant reduction (*p< 0.05) in plasma levels of total cholesterol and LDL-cholesterol with no significant change (*p> 0.05) in HDL-cholesterol, triglyceride and VLDL levels in the plasma at all doses of polyphenols administered compared to controls. There was significant reduction (*p< 0.05) in the activities of heart AST and LDH while plasma ALT, AST, and ALP activities were not significantly altered (*p> 0.05) at all doses of polyphenols administered compared to controls. These results suggest that the polyphenols of C. nucifera husk fibre possess cardio-protective properties and also indicate their possible use in the treatment of cardiovascular diseases.

  • Objective: Incorporating high fibre ingredients into pig diets has the potential to reduce odour emissions from of pigs. The current study was carried out to determine effect of diets containing 0, 80 and 160 g/kg of each of lucerne hay, maize cobs and sunflower husks on the chemical characteristics and odours from pig slurries. Methods: Twenty eight pigs averaging $18{\pm}2.0kg$ were kept in individual cages, over four weeks. All pigs were fed ad libitum. Faeces and urine were collected, mixed in a 1:2.3 ratio (w/w), stored and fermented for 16 days in a temperature controlled room at $22^{\circ}C{\pm}2.3^{\circ}C$. The slurry was sampled twice (on day 1 and on day 16) of the fermentation period and analysed for pH, chemical oxygen demand (COD), nitrogen and short chain fatty acids (SCFA) concentration, on wet basis. All samples were tested for odour offensiveness using 18 panelists. A scale of 1 to 5 was used to rank the odour severity, (1 = not offensive, 5 = extremely offensive). Results: Slurry pH and COD varied with fibre source (p<0.05). On day 16, COD for lucerne hay, sunflower husk and maize cobs were 369, 512, and 425 (standard error of the mean = 34.2) mg of oxygen per litre. Total SCFA concentration was higher at day 16 than day 1 (p<0.05). Odour offensiveness varied with fibre source across both incubation periods (p<0.05). Sunflower husks and lucerne hay-based diets were rated as less offensive (mean rank = 2.2) than maize cob diets (mean rank of 4.3) (p<0.05). Conclusion: It was concluded that different fibre sources and incubation period influence chemical composition and odour of the slurry. There is, thereby, a need to incorporate locally available fibrous feeds in the diet of pigs because they have an economical and environmental relevance to pig management.
