While being important food sources at community level, IFs and their by- Indigenous fruit products are also incorporated into medicinal remedies, combating various diseases. Their ethnomedicinal usage Bioeconomy indicates potent bioactive profile that alleviate effects of oxidative stress, which accompany diseasein vivo. This is supported by in vitro antioxidant activity of the IFs and their byproducts. As such, the current review explores the potential of bioprospecting extracts from nine IFs and their byproducts as food antioxidants. Evidence presented shows that IFs have high content of bioactive compounds further translating to high antioxidant activity. Research gaps in information concerning in vitro bioactivity warrant further research to provide impetus for valorisation and food application of IFs.
