Evaluation of phytochemicals bioavailability and antioxidant capacity in South African common indigenous foods

Phytochemicals are secondary metabolites that offer biological activity to prevent degeneration of different non-communicable diseases such as type-2 diabetes (Stroke), cardiovascular disease, and cancer. Indigenous food crops are rich source of phytochemicals such as phenolic acids and flavonoids which have demonstrated some biological activities including antioxidant, anti-inflammation and anti-bacterial effect. This study aims to screen phytochemical profile in three indigenous food crops [Amaranthus species, Okra (Abelmoschus esculentus (L.) Moench) and cowpea grain (Vigna unguiculata (L.) Walp.)]. Both untargeted and targeted metabolites profile analysis will be performed to identify the predominant bio-maker or analyte (s). Then the identified analytes will further be analysed for bioaccessibility in to the in vitro gastro-intestinal tract to observe digestion impact on phenolic compounds bioavailability. Three manuscripts in relation to polyphenol bioavailability are expected from this study.
