Combined analysis of Xylopia aethiopica trunk bark oil by chromatographic and spectroscopic techniques

Abstract: 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 was dominated by βpinene (37.0-61.6%) and α-pinene (13.0-19.3%). Two samples out of four contained also 3,3-dimethyl-1vinylcyclohexene (up to 6.4%) and 4,4-dimethyl-2-vinylcyclohexene (up to 12.7%).

Neuroprotective Effect of Xylopia Aethiopica Seed on Lead-Induced Injury on the Cerebral Cortex of Male Wistar Rat

Abstract: Background: Lead (Pb) is one of the most common environmental toxicants, exposure to which can cause significant neurotoxicity and an associated decline in brain function. Plant derived products with antioxidants activity are useful in reducing lead induced neurotoxicity. This study investigated neuroprotective and antioxidant properties of the aqueous Xylopia aethiopica against lead -induced neurotoxicity in male Wistar rats. Methods: Six groups of six weight-matched animals each, were used for the study. The group 1 (normal control) was treated with distilled water and group 2 (toxic control) with lead acetate at the doses of 50 mg/kg b.wt, whereas group 3 received only Xylopia aethiopica 40 mg/kg only, groups 4, 5, and 6 were simultaneously treated with lead (50 mg/kg b.w.), and 40mg/kg, 80mg/kg, and 160mg/kg of Xylopia aethiopica respectively The treatment was administered orally for 42 days. Their biochemical and histopathological investigations were carried out following animal sacrifice at the end of the study period. The neuroprotective effect of Xylopia aethiopica was assessed by measuring redox status (malondialdehyde), enzymatic antioxidant activities (Superoxide dismutase, Catalase, Glutathione peroxidase and glutathione reductase) and histopathology of the cerebral cortex. Results: The increase in the malondialdehyde, the decrease in the activity of antioxidant enzymes (Catalase, Glutathione peroxidase and reductase), and the altered histology of the brain induced neurotoxicity by lead acetate were mitigated in the brain of rats treated with Xylopia aethiopica. Conclusion: Aqueous Xylopia aethiopica has a neuroprotective role against lead - induced neurotoxicity probably mediated through its antioxidant properties.

Effect of Xylopia aethiopica Dried Fruits (Grains of Selim) as Additive on Performance, Microbial Response and Blood Parameters in Finisher Broilers

Abstract: The effect of grains of selim ( Xylopia aethiopica ) as additive on the performance, gut microbes and blood parameters of finisher broilers was investigated. One hundred and ninety five (195) 28 days old broilers (Arbor acres strain) were randomly assigned to five treatment groups with each treatment having three replicates in a completely randomized design. Each treatment group had 39 chicks and 13chicks per replicate. The experiment was done in the Poultry Research Unit of the Department of Animal Science, Delta State University, Asaba Campus, Nigeria between November 2013 and January 2014. Well homogenized powdered grains of selim was dissolved and given through drinking water in treatments 2, 3, 4 and 5 at concentrations of 0.4, 0.6, 0.8 and 1.0 g per litre but chicks on treatment 1 (control) received 0.3 g/litre of antibiotics (doxygen). Chicks were fed with isoproteinous and isocaloric diets with 20% crude protein and 2905.95 Kcal/kg meta bolizable energy ad libitum for four weeks. Results showed no significant differences among treatments in the final body weight, total weight gain, daily weight gain, total feed intake, daily feed intake and feed

Effect of preservation with Xylopia aethiopica on the shelf life of cowpea seeds.

Abstract: A popular cowpea variety-Ife-brown was used for experiments. Optimal concentration of Xylopia aethiopica required for storage of whole cowpea seeds was determined in petri dishes. Whole cowpea seeds were stored in white and black polyethylene bags [WPB and BPB), clay pots (CP) and plastic cans (PC) using 0.5 g Xylopia aethiopica dust per 100 g cowpeas. Physico-chemical properties of the seeds were monitored on a biweekly basis for 24 weeks. By the end of the storage period, increase in the moisture content of cowpeas stored in PC was found to be the lowest (38%). while that of BPB was the highest (205%). Seeds stored in PC retained 92% of their viability, while those stored in BPB were no longer viable. Seeds stored in CP had the highest number of insect emergent holes. Reconstitutability and foam properties of cowpea seeds stored in BPB and CP were markedly lowered. PC and WPB were better storage containers than CP and BPB. Seeds stored with X. aethiopica were more acceptable than controls.
