Recent results from natural product research at the University of Botswana
(IUPAC. http://www.iupac.org/publications/pac/, 2001)
Marketed plants are very important items of trade in many parts of the world. The
community uses these for a variety of purposes such as foods, cosmetics, flavors, spices, and
medicines. It seems that plants that are ...
Fire and its influence on microbial community structure and soil biochemical properties in the Okavango Delta, Botswana
(Academic Journals. http://www.academicjournals.org/SRE, 2007)
The influence of wild fires on microbial community structure, soil organic matter, sulphur oxidising and
nitrifying microbial populations in the floodplains of the Okavango Delta of Botswana was assessed.
Microbial ...
Prenylated flavonoids, monoterpenoid furanocoumarins and other constituents from the twigs of Dorstenia elliptica (Moraceae)
(Elsevier Ltd. www.elsevier.com/locate/phytochem, 2003)
A monoprenylated flavan and two monoterpenoid substituted furanocoumarins were isolated from the twigs of Dorstenia elliptica
along with 3-(3,3-dimethylallyl)-4,20,40-trihydroxylchalcone, psoralen, bergapten, O-[3-(2,2- ...
Prenylated arylbenzofuran derivatives from Morus mesozygia with antioxidant activity
(Elsevier Ltd. www.elsevier.com/locate/phytochem, 2008)
Five prenylated arylbenzofurans, moracins Q–U, were isolated from Morus mesozygia (Moraceae). Their
structures were elucidated on the basis of spectroscopic evidence. Along with these compounds, 3b-acetoxyurs-
12-en-11-one, ...
Rotenoid derivatives and other constituents of the twigs of Millettia duchesnei
(Elsevier Ltd. www.elsevier.com/locate/phytochem, 2007)
Three prenylated rotenoids, elliptol, 12-deoxo-12a-methoxyelliptone and 6-methoxy-6a,12a-dehydrodeguelin were isolated from the
twigs of Millettia duchesnei, together with the known compounds, 6a,12a-dehydrodeguelin, ...
Single-electron states near a current-carrying core
(Elsevier Science Ltd. http://www.elsevier.com/locate/physb, 2004)
The energy spectrum of an electron confined near a current-carrying core is obtained as a function of the azimuthal
applied magnetic field within the effective-mass approximation. The double degeneracy of the non-zero ...
Plant alkali content and radio wave communication efficiency in high intensity savanna wildfires
(Elsevier Science Ltd. www.elsevier.com/locate/jastp, 2007)
The flames of wildfires are weakly ionized gas. The ionization is mainly due to omnipresent alkali and alkaline earth
metal species that are emitted from thermally decomposing plant structure into the flame during a ...
The effects of the water management framework and the role of domestic consumers on urban water conservation in Botswana
(Routledge http://dx.doi.org/10.1080/02508060802475415, 2008)
This article examines the adverse effects of a fragmented water management framework and
the role of domestic water users on water conservation in Gaborone, the rapidly growing
capital city of Botswana. There was a major ...
Photon interaction cross sections in the low energy region in Mg and V
(Elsevier Science Ltd. www.elsevier.com/locate/radphyschem, 2004)
The interaction of photons with matter has been
extensively studied over the past several decades in view
of its importance in basic radiation physics research,
medical, industrial and other applied fields. Large
amounts ...
Stereoselective routes to 3-hydroxy and 3,4-dihydroxy derivatives
(Elsevier Ltd; www.elsevier.com/locate/tetlet, 2004-06-21)
The Diels-Alder adduct of ethyl (E)-3-nitroacrylate and furan provides a versatile template for the stereoselective synthesis
of mono and dihydroxylated derivatives of 2-aminocyclohexanecarboxylic acid (ACHC). The ...
