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
