Characterization of fatty acids in the roots of Cryptolepis sanguinolenta

Opoku-Boahen, Y.; Barku, V. Y. Atsu; Dobson, Andrew (University of Cape Coast, 2011)

The roots of Cryptolepis saguinolenta were extracted with petroleum ether (40–60C) to afford the oil in 0.7% yield to the wet mass of raw material. The fatty acid methyl esters (FAME) were separated and analyzed by GC-MS. ...
ISOLATION OF ent-LABDANE (+)-12,15-EPOXYLABDA-8(17), 12,14-TRIEN-16-YL ACETATE FROM THE SEEDS OF Turraeanthus africanus AND ITS CYTOSTATIC/CYTOTOXIC EFFECT ON THE GROWTH OF CANCER CELLS in vitro

Tayman, F. S.; Barku, V. Y. Atsu; Opoku-Boahen, Y.; Seifert, K.; Grote, D. (University of Cape Coast, 2006)

(+)-12,15-Epoxylabda-8(17),12,14-trien-16-yl acetate has been isolated from the seed kernels of Turraeanthus africanus (Nelw. ex DC). The stereo structure was confirmed by 1D- and 2D-NMR spectroscopy. Cytostatic/cytotoxic ...
