摘要

<em>Dioscorea</em><span style="font-family:;" "=""><span style="font-family:Verdana;"> spp., White Yam has been shown to exhibit a wide range of nutritional and medicinal properties. However, the compounds associated with its medicinal functions have not been fully examined. The purpose of this study was to generate a chemoinformatic profile of the bioactive compounds present in </span><i><span style="font-family:Verdana;">Dioscorea</span></i><span style="font-family:Verdana;">. </span><i><span style="font-family:Verdana;">alata</span></i><span style="font-family:Verdana;"> (</span><i><span style="font-family:Verdana;">D</span></i><span style="font-family:Verdana;">. </span><i><span style="font-family:Verdana;">alata</span></i><span style="font-family:Verdana;">) and to characterize their putative anti-cancer properties using prostate (DU145) and lung (A549) cancer cells. Chemoinformatic profiling of </span><i><span style="font-family:Verdana;">D</span></i><span style="font-family:Verdana;">. </span><i><span style="font-family:Verdana;">alata</span></i><span style="font-family:Verdana;"> resulted in five bioactive extracts</span></span><span style="font-family:Verdana;">:</span><span style="font-family:Verdana;"> hexane (DaJa-1), ether (DaJa-2), acetone (DaJa-3), ethanol (DaJa-4) and water (DaJa-5) were generated. The analytes present in the five bioactive extracts were dissolved in 0.1% DMSO and their anti-cancer activity </span><span style="font-family:Verdana;">were </span><span style="font-family:Verdana;">determined.
