The chemistry and biological activity of the Hyacinthaceae.
The Hyacinthaceae (sensu APGII), with approximately 900 species in about 70 genera, can be divided into three main subfamilies, the Hyacinthoideae, the Urgineoideae and the Ornithogaloideae, with aExpand
Bioactive compounds from Combretum erythrophyllum.
A methanol extract of Combretum erythrophyllum showed inhibitory bioactivities in a yeast-based microtiter assay for DNA-damaging agents. Bioassay-guided fractionation of this extract yielded twoExpand
Phaeophytins from Tapura fischeri
Abstract The ethyl acetate extract of the leaves of Tapura fischeri yielded four novel phaeophytins, 17 3 -ethoxyphaeophorbide a, phaeophytin a-13 2 -carboxylic acid, 17 3 -ethoxy-phaeophorbide a-13Expand
Diterpenoids from the roots of Croton dichogamus Pax.
Four previously undescribed diterpenoids including two crotofolanes, crotodichogamoin A and B, and two halimanes, crothalimene A and B, a new sesquiterpenoid, and fifteen previously reportedExpand
Delevoyin C, a tetranortriterpenoid from Entandrophragma delevoyi.
The hexane extract of the bark of Entandrophragma delevoyi has yielded a novel tetranortriterpenoid, delevoyin C. This compound contains a cyclobutanyl ring incorporating C-19 and a cycloheptanylExpand
Antimalarial activity of plant metabolites.
This review covers the structures of compounds with antiplasmodial activity isolated from plants and is organized according to plant family. A total of 170 structures has been reviewed from 186Expand
The Effect of Aromatic Ethers on the Trimerisation of Ethylene using a Chromium Catalyst and Aryloxy Ligands
A catalyst system consisting of a chromium source, a 2,6-disubstituted phenol and an aromatic ether solvent, on activation with triethylaluminium, is active and selective for the trimerisation ofExpand
Limonoid derivatives from Astrotrichilia voamatata.
The stem bark of Astrotrichilia voamatata (Meliaceae) has yielded the novel limonoids voamatins C and D. These compounds represent a new type of pentanortriterpenoid and are unique in containing aExpand
Antiangiogenic Activity and Cytotoxicity of Triterpenoids and Homoisoflavonoids from Massonia pustulata and Massonia bifolia.
The Hyacinthaceae family (sensu APGII), with approximately 900 species in around 70 genera, plays a significant role in traditional medicine in Africa as well as across Europe and the Middle and FarExpand
