Abstract (EN): Among several extracts from species from Guinea-Bissauan flora, the hydroethanol extract obtained from the leaves of gingerbread plum (Neocarya macrophylla (Sabine) Prance ex F. White.) revealed to be one of the most cytotoxic towards human gastric AGS carcinoma cells.& nbsp;Considering the increasing use of N. macrophylla in the food industry and the abundant biomass of agricultural wastes being generated, the identification of phenolic bioactives has been attained by HPLC-DAD-ESI/MSn and UHPLC-ESI/QTOF/MSn. Twenty-seven phenolic constituents were identified for the first time in the monotypic genus Neosartorya, 5-O-caffeoylquinic acid being detected as the major constituent (4.90 & PLUSMN; 0.20 mg g-1 dry extract). While 15 flavan-3-ols derivatives were determined, the extract is predominantly characterized by the occurrence of quercetin, kaempferol, apigenin and chrysoeriol glycosides.& nbsp;Typical apoptotic changes in gastric adenocarcinoma AGS cells upon exposure to N. macrophylla leaf extract were observed.The apoptotic cell death is mediated by the activation of the mitochondrial pathway, as loss of mitochondrial membrane potential was detected, as well as increased caspase-9 and-3 activities.& nbsp;The industrial relevance of this plant material, along with the data presented here on the potential anticancer effects of N. macrophylla and the efficient extraction of phenolic bioactives using water and ethanol (GRAS substance), calls for further research on the leaves as a potential functional food and/or ingredient.
