3b-Taraxerol from Bridelia micrantha
(2009-02-13)
Isolation of the title compound, C30H50O, from Bridelia
micrantha yielded suitable crystals for an X-ray structure
determination, showing it to be in the -form. The crystal
packing is determined by infinite zigzag O—H ...

Origins of strandline duricrusts around the Makgadikgadi Pans (Botswana Kalahari) as deduced from their chemical and isotope composition
(Elsevier www.elsevier.com/locate/sedgeo, 2009)
Trace elements togetherwith some O and C isotope analysiswere undertaken on duricrust strandline deposits in
the palaeo-Makgadikgadi sub-basin (PMSB) to provide insight into palaeo-climatic conditions through the
interpretation ...
