nutritional evaluation of crude palm oil in rats.edible-grade crude palm oil (cpo: from elaeis guineensis) is one of the richest natural sources of beta-carotene (7500 mumol/l) and is cheaper than other edible oils, making it a promising source of vitamin a in a deficient population. nutritional studies were conducted on weanling albino rats of the wistar/nin strain for 28 and 90 d. diets contained 10% of either cpo, groundnut oil (gno), or refined palm-olein oil (rpo) and adequate amounts of all other nutrients. no adverse effects were observ ...19912012012
dietary responses to fruit scarcity of wild chimpanzees at bossou, guinea: possible implications for ecological importance of tool use.a 13-month ecological study was conducted at bossou, guinea, west africa, to elucidate how a community of wild chimpanzees (pan troglodytes verus) deals with the scarcity of main foods. during the study period, fruit availability fluctuated radically. the chimpanzees were confirmed to depend heavily on three "keystone resources" which were available when their main foods (fruit pulp) were scarce. these were fruits of musanga cecropioides, oil-palm (elaeis guineensis) nuts, and oil-palm pith. the ...19989696145

white-faced monkey (cebus capucinus) ecology and management in neotropical agricultural landscapes during the dry season.habitat use by a c. capucinus troop was studied in an agricultural landscape during late dry season (march-april 1994) in northwest costa rica. riparian forests, palm canals and living fence rows accounted for 82% of observations, significantly more than the other six habitats present. the study troop consumed 24 species of plants and five animals. feeding concentrated on the introduced african oil palm (elaeis guineensis) (33.6%) and mango (mangifera indica) (27.2%), found mostly in palm canals ...200112189802
palm oil: biochemical, physiological, nutritional, hematological, and toxicological aspects: a review.the link between dietary fats and cardiovascular diseases has necessitated a growing research interest in palm oil, the second largest consumed vegetable oil in the world. palm oil, obtained from a tropical plant, elaeis guineensis contains 50% saturated fatty acids, yet it does not promote atherosclerosis and arterial thrombosis. the saturated fatty acid to unsaturated fatty acid ratio of palm oil is close to unity and it contains a high amount of the antioxidants, beta-carotene, and vitamin e. ...200212602939
comparison of the effect of two excipients (karite nut butter and vaseline) on the efficacy of cocos nucifera, elaeis guineensis and carapa procera oil-based repellents formulations against mosquitoes biting in ivory coast.repellents in the form of dermal pomades are recommended as a protection against awakening and bedtime mosquito bites. if synthesis repellents are available, they are nevertheless not common and the prices remain out of reach for the communities concerned. the people therefore have to resort more and more to traditional concoctions, some of which have been shown to be effective. after demonstrating that oil-based formulations (lotions, creams, pomades) of cocos nucifera (coconut), elaeis guineen ...200312847928

microbial degradation of palm (elaeis guineensis) biodiesel.the kinetics of biodegradation of palm-derived fatty methyl and ethyl esters (elaeis guineensis biodiesel) by a wild-type aerobic bacterial population was measured at 20 degrees c, as the rate of oxygen uptake by a manometric technique. the methyl and ethyl biodiesels were obtained by potassium-hydroxide catalysed trans-esterification of palm oil, respectively. the bacterial flora included the genera bacillus, proteus, pseudomonas, citrobacter and enterobacter. the rate of oxygen uptake for palm ...200618457175
birds defend oil palms from herbivorous insects.top-down forces are expected to be important in regulating herbivore populations in most agricultural systems where primary productivity is high and species diversity is low. under such conditions, trophic cascades are predicted to occur when predator populations are reduced or removed. studies on how predator removal indirectly affects herbivory rates in agricultural systems are lacking. through a bird-exclosure experiment, i test the hypothesis that insectivorous birds indirectly defend oil pa ...200818536244

(coleoptera: curculionidae).the occurrence of the tachinid parasitoid billaea rhynchophorae (blanchard) on larvae of the palm weevil rhynchophorus palmarum (l.) was evaluated in plantations of piassava palm (attalea funifera mart.) and african oil palm (elaeis guineensis jacquin), in southeastern bahia, brazil. the monthly percentages of parasitism were evaluated during 13 months, from november 2000 to november 2001, based on the comparison between the number of parasitized and non-parasitized cocoons of r. palmarum. mean ...200617348142
the effects of provisioning and crop-raiding on the diet and foraging activities of human-commensal white-faced capuchins (cebus capucinus).non-human primates are coming into increasingly frequent contact with humans and with human-modified environments. the potential for monkeys to survive in such modified landscapes is questionable, and is likely related to a species' behavioral plasticity, particularly as it relates to diet. in this study, i explore the ways in which white-faced capuchins (cebus capucinus) adjust their diet and foraging behaviors in response to anthropogenic impact. i compare a troop of human-commensal monkeys an ...201121432873
growth of yeasts, lactic and acetic acid bacteria in palm wine during tapping and fermentation from felled oil palm (elaeis guineensis) in ghana.to investigate the microbiological and biochemical changes which occur in palm wine during the tapping of felled oil palm trees. methods and results: microbiological and biochemical contents of palm wine were determined during the tapping of felled oil palm trees for 5 weeks and also during the storage. saccharomyces cerevisiae dominated the yeast biota and was the only species isolated in the mature samples. lactobacillus plantarum and leuconostoc mesenteroides were the dominated lactic acid ba ...200717241367
assaying lipase activity from oil palm fruit (elaeis guineensis jacq.) mesocarp.the mesocarp of mature oil palm fruit undergoes intensive triglycerides hydrolysis upon abscission and bruising. this generates such a high amount of free fatty acids that the oil might become unfit for human consumption without appropriate refining. the lipase (ec 3.1.1.3) involved in the breakdown of the oil is not stable after homogenization of the tissue in aqueous buffers. in this study, we have devised a solvent-based procedure that allowed us to obtain fractions with stable lipase activit ...200617064925

phytonutrient deficiency: the place of palm fruit.the oil palm (elaeis guineensis) is native to many west african countries, where local populations have used its oil for culinary and other purposes. large-scale plantations, established principally in tropical regions (asia, africa and latin america), are mostly aimed at the production of oil, which is extracted from the fleshy mesocarp of the palm fruit, and endosperm or kernel oil. palm oil is different from other plant and animal oils in that it contains 50% saturated fatty acids, 40% unsatu ...200314506002
characterisation of copia-like retrotransposons in oil palm ( elaeis guineensis jacq.).the work aimed to isolate and characterise copia-like sequences from elaeis guineensis. thirty-two different rt (reverse transcriptase) sequences were isolated from a single oil palm genome using degenerate primers. extreme sequence heterogeneity was observed. the dna and protein sequences were assigned to three different classes (a, b, c) on the basis of bootstrapping. we estimated the copy number of the three different classes by using a dot-blot analysis. the comparative results suggest that ...200212582647
polyphenol-enriched extract of oil palm fronds (elaeis guineensis) promotes vascular relaxation via endothelium-dependent mechanisms.plant-based polyphenolic compounds have been reported to possess cardiovascular health benefits. several dietary sources, including herbs and spices, fruits and vegetables, and tea and wine, contain an array of biologically active compounds that have been shown to be effective in retarding oxidation of low-density lipoproteins (ldl) and promoting vascular relaxation. in the present study four different plant sources, both edible and non-edible, were evaluated for potential activity. organic extr ...200212492636
