Canarium Schweinfurthii)
International Journal of Advanced Research in Chemical Science (IJARCS) Volume 2, Issue 11, November 2015, PP 34- 36 ISSN 2349-039X (Print) & ISSN 2349-0403 (Online) www.arcjournals.org Characterization of African Elemi (Canarium Schweinfurthii) Maduelosi N.J and Angaye S.S Department of Chemistry, Rivers State University of Science and Technology, Nkpolu Oroworukwo, P M B 5080, Port Harcourt [email protected] Abstract: The physicochemical and proximate compositions of African Elemi were investigated by analyzing the moisture, crude protein, crude fat, ash content, crude fibre and total carbohydrates in the seed and pulp. The association of official analytical chemists (AOAC, 1990) methods were used. Values obtained for the physicochemical and proximate analysis of whole seeds and pulps were; seed length( 4.5cm and 6.0cm), thickness (4.0cm and 6.0cm),shape (oblong),free fatty acid content (3.52% and 3.28%), miv (1.72% and 1.70%),melting point (32oC and 30oC),moisture (25.62% and 26.09%), dry matter, ash (3.14% and 3.31), crude fat (30.06% and 30.56%), crude fibre (0.76% and 0.78%), carbohydrate (20.03% and 20.05% ), protein (19.28% and 19.31%). The results suggest that the whole seeds and pulp of African elemi (Canarium schweinfurthii ), can serve as a good source of essential nutrients for humans and livestock. KeyWords: African Elemi, Canarium schweinfurthii, pulp, seeds, proximate and physiochemical parameters. 1. INTRODUCTION The exploitation of several underutilized wild fruits and oilseeds as sources of vegetable protein, fats and vitamin C to augment supplies from the inadequate animal sources has been reported by several authors (Olaofe 1994, Ikhuoria and Maliki 2007, Dike 2010, Igidi and Edene 2014). -
Diversification of Tree Crops: Domestication of Companion Crops for Poverty Reduction and Environmental Services
Expl Agric. (2001), volume 37, pp. 279±296 Printed in Great Britain Copyright # 2001 Cambridge University Press REVIEW PAPER DIVERSIFICATION OF TREE CROPS: DOMESTICATION OF COMPANION CROPS FOR POVERTY REDUCTION AND ENVIRONMENTAL SERVICES By R. R. B. LEAKEY{ and Z. TCHOUNDJEU{ {Centre for Ecology and Hydrology, Bush Estate, Penicuik, Midlothian, EH26 0QB, Scotland, UK and {International Centre for Research in Agroforestry, PO Box 2067, YaoundeÂ, Cameroon (Accepted 19 January 2001) SUMMARY New initiatives in agroforestry are seeking to integrate indigenous trees, whose products have traditionally been gathered from natural forests, into tropical farming systems such as cacao farms. This is being done to provide from farms, marketable timber and non-timber forest products that will enhance rural livelihoods by generating cash for resource-poor rural and peri-urban households. There are many potential candidate species for domestication that have commercial potential in local, regional or even international markets. Little or no formal research has been carried out on many of these hitherto wild species to assess potential for genetic improvement, reproductive biology or suitability for cultivation. With the participation of subsistence farmers a number of projects to bring candidate species into cultivation are in progress, however. This paper describes some tree domestication activities being carried out in southern Cameroon, especially with Irvingia gabonensis (bush mango; dika nut) and Dacryodes edulis (African plum; safoutier). As part of this, fruits and kernels from 300 D. edulis and 150 I. gabonensis trees in six villages of Cameroon and Nigeria have been quantitatively characterized for 11 traits to determine combinations de®ning multi-trait ideotypes for a genetic selection programme. -

Resistance of Salmonella to commonly used antimicrobials is increasing both in the veterinary and human health sectors and has emerged as a global problem. This resistance has been linked to the inappropriate use of antibiotics, especially in poultry farm. New control strategies of salmonellosis are needful. This study therefore aimed at evaluating in vitro antisalmonellal and antioxidant power of a medicinal plant, Canarium schweinfurthii Engl. (Burseraceae) commonly used as antityphoid plant in oder to implement it in poultry farm. For antisalmonellal assay, serial microdilution method was used to determine the MIC and MBC of plants extracts against four isolates and one strain of Salmonella; the antioxidant activities of the extracts, as well as the phytochemical screening, were performed using different standard methods. The result showed that most of the extracts exhibited minimum inhibitory concentrations (MICs) ranging from 64 to 1024 1 Jean Baptiste Sokoudjou , Guy Sedar µg/ml; ethanolic and hydro-ethanolic extract being the most effective as compared Singor Njateng1, Siméon Pierre Chegaing Fodouop2, Norbert Kodjio1, Serge Secco with aqueous extracts. As far as the antioxidant activities are concerned, all the Atsafack1, Alain Bertrand Fowa1, Merline tested concentrations of ethanolic and hydro-ethanolic extracts exhibited good Namekong Djimeli1 and Donatien DPPH scavenging activities as compared with the aqueous extracts. -

The phylogenetic component of diversity has been particularly difficult to quantify in species-rich tropical tree assemblages. The compilation of previously published (and often incomplete) data on evolutionary relationships of species into a composite phylogeny of the taxa in a forest, through such programs as Phylomatic, has proven useful in building community phylogenies although often of limited resolution. Recently, DNA barcodes have been used to construct a robust community phylogeny for nearly 300 tree species in a forest dynamics plot in Panama using a supermatrix method. In that study sequence data from three barcode loci were used to generate a well-resolved species- level phylogeny. Methodology/Principal Findings: Here we expand upon this earlier investigation and present results on the use of a phylogenetic constraint tree to generate a community phylogeny for a diverse, tropical forest dynamics plot in Puerto Rico. -
The Monophyly of Bursera and Its Impact for Divergence Times of Burseraceae
TAXON 61 (2) • April 2012: 333–343 Becerra & al. • Monophyly of Bursera The monophyly of Bursera and its impact for divergence times of Burseraceae Judith X. Becerra,1 Kogi Noge,2 Sarai Olivier1 & D. Lawrence Venable3 1 Department of Biosphere 2, University of Arizona, Tucson, Arizona 85721, U.S.A. 2 Department of Biological Production, Akita Prefectural University, Akita 010-0195, Japan 3 Department of Ecology and Evolutionary Biology, University of Arizona, Tucson, Arizona 85721, U.S.A. Author for correspondence: Judith X. Becerra, [email protected] Abstract Bursera is one of the most diverse and abundant groups of trees and shrubs of the Mexican tropical dry forests. Its interaction with its specialist herbivores in the chrysomelid genus Blepharida, is one of the best-studied coevolutionary systems. Prior studies based on molecular phylogenies concluded that Bursera is a monophyletic genus. Recently, however, other molecular analyses have suggested that the genus might be paraphyletic, with the closely related Commiphora, nested within Bursera. If this is correct, then interpretations of coevolution results would have to be revised. Whether Bursera is or is not monophyletic also has implications for the age of Burseraceae, since previous dates were based on calibrations using Bursera fossils assuming that Bursera was paraphyletic. We performed a phylogenetic analysis of 76 species and varieties of Bursera, 51 species of Commiphora, and 13 outgroups using nuclear DNA data. We also reconstructed a phylogeny of the Burseraceae using 59 members of the family, 9 outgroups and nuclear and chloroplast sequence data. These analyses strongly confirm previous conclusions that this genus is monophyletic. -

KOLAWOLE Department of Forestry, Wildlife and Fisheries Management, Ekiti State University, Ado-Ekiti, Nigeria. *Corresponding author: [email protected], +2348034811371. ABSTRACT Four hundred and fifty seeds of Dacryodes edulis were extracted from mature fruits obtained from the same source. These were divided into five parts and subjected to five treatments thus: T1: Fresh; T2: 7 days storage; T3: 14 days storage; T4: 21 days storage and T5: 28 days storage. Storage was done at room temperature. Each part was weighed in three replicates and then sown in germination box filled with topsoil. Analysis of Variance showed significant difference in seed weight at α = 0.05 although Duncan’s Multiple Range Test revealed that T1 and T2 were not significantly different from each other. Germination was observed on the 17th Day after Sowing (DAS), 21 DAS and 24 DAS for T1, T2 and T3 respectively. Furthermore, T1 had the highest germination percentage of 96.7%, followed by T2 with a value of 70.0% while T3 had the least value of 36.7%. However, seeds in T4 and T5 did not germinate till the experiment was concluded. This study revealed that as length of storage increased, viability of Dacryodes edulis seeds reduced and this knowledge is crucial to its domestication. Keywords: seed viability, storage, germination, non-timber forest products. INTRODUCTION The fruits of Dacryodes edulis are a delicacy among the people of Southern Nigeria where it is consumed as an accompaniment with fresh maize (Agbogidi and Eshegbeyi, 2006). -
The Biogeographic Origin of a Radiation of Trees In
Federman et al. BMC Evolutionary Biology (2015) 15:216 DOI 10.1186/s12862-015-0483-1 RESEARCHARTICLE Open Access The biogeographic origin of a radiation of trees in Madagascar: implications for the assembly of a tropical forest biome Sarah Federman1*, Alex Dornburg2, Alexander Downie1, Alison F. Richard3, Douglas C. Daly4 and Michael J. Donoghue1 Abstract Background: Madagascar’s rain forests are characterized by extreme and uneven patterns of species richness and endemicity, the biogeographic and evolutionary origins of which are poorly understood. Methods: Here we use a time-calibrated phylogeny of a dominant group of trees in Madagascar’seastern rain forests, Canarium, and related Burseraceae (Canarieae), to test biogeographic hypotheses regarding the origin and radiation of the flora of this unique biome. Results: Our findings strongly support the monophyly of Malagasy Canarium, suggesting that this clade represents a previously undocumented in situ radiation. Contrary to expectations of dispersal from Africa during the Oligocene, concurrent with the formation of Madagascar’s rain forest biome, our analyses support a late Miocene origin for Malagasy Canarium, probably by long distance dispersal from Southeast Asia. Discussion: Our study illustrates the importance of considering long distance dispersal as a viable explanation for clades with pantropical distributions diversifying subsequent to the Oligocene, and it highlights the formation of the Indo-Australian Archipelago and associated fast-moving equatorial surface currents, suggesting an under-appreciated evolutionary link among tropical centers of endemism. Conclusions: We postulate that the relatively recent establishment and radiation of Canarium in Madagascar may have been facilitated by the highly stochastic climates associated with these forest ecosystems. -

Dacryodes Excelsa Vahl Tabonuco Burseraceae Bursera Family
Dacryodes excelsa Vahl Tabonuco Burseraceae Bursera family Ariel E. Lugo and Frank H. Wadsworth Tabonuco (Dacryodes excelsa), also known as gom- mier and candlewood, is the dominant large tree of the native forests that formerly covered the northern lower and middle slopes of the mountains of Puerto Rico. It is distinguished by broad low buttresses, a columnar bole, smooth gray bark, and pinnately com- pound leaves with five to seven fragrant, dark-green leaflets. When wounded, the tree exudes a clear, fragrant inflammable resin that hardens and turns white on exposure. Habitat Native Range Tabonuco (fig. 1) is native to elevations from 200 to 900 m (660 to 2,800 ft) throughout Puerto Rico. On favorable sites, it may make up 35 percent of the basal area and 80 percent of the timber volume of the forest, commonly termed Dacryodes-Sloanea as- sociation (1). From Puerto Rico, the native range of tabonuco extends into the Lesser Antilles on St. Kitts, Montserrat, Guadeloupe, Dominica, Martini- que, St. Lucia, St. Vincent, and Grenada, a gross forest area of about 2300 km* (888 mi*) (24). Other members of the genus are in South America and Africa (5,s). Climate Tabonuco in Puerto Rico is found within a mean Figure 1-A mature tabonuco showing spreading crown. temperature range of 21” to 25” C (70” to 77” F) and a mean annual precipitation range from 2000 to 4000 mm (79 to 157 in). Precipitation is generally abun- fall, 3700 mm (146 in). Diurnal variations are dant except from February through April, when it smaller than some seasonal changes (16).
