- ItemAntioxidant activity, total phenols and phytochemical constituents of four underutilised tropical fruits(International Food Research Journal, 2015) Boakye, Abena A.; Wireko-Manu, Faustina D.; Agbenorhevi, Jacob K.; Oduro, Ibok N.; 0000-0003-0344-2683; 0000-0002-5020-6299; 0000-0002-8516-7656; 0000-0003-3731-2684The antioxidant activity, total phenols content and phytochemical constituents of edible portions of four underutilised tropical fruits; Irvingia gabonensis (African mango), Artocarpus altilis (breadfruit), Annona muricata (soursop) and Annona squamosa (sweetsop) were determined. Extracts of fruit samples were screened for selected phytochemicals using standard methods whereas the total phenols content and antioxidant activity (by free radical scavenging action) was determined by the Folin-Ciocalteu method and DPPH assay, respectively. The antioxidant activities were high with values ranging from 63% inhibition (breadfruit) to 78% inhibition (African mango pulp). African mango seeds had the highest total phenols content (20.96 mg GAE /100g). Tannins, triterpenoids, saponins, sterols, cardiac glycosides, flavanoids and coumarins were detected in most of the fruit extracts. The study revealed that these underutilised tropical fruits have considerable free radical scavenging (antioxidant) activity and an array of phytochemicals necessary to significantly impact health of consumers.
- ItemDietary fibre ascorbic acid and proximate composition of tropical underutilised fruits(African Journal of Food Science, 2014-06) Boakye, Abena A.; Wireko-Manu, Faustina D.; Agbenorhevi, Jacob K.; Oduro, Ibok N.; 0000-0003-0344-2683; 0000-0002-5020-6299; 0000-0002-8516-7656; 0000-0003-3731-2684The current surge in the prevalence of chronic diseases has necessitated the call for the increased consumption of fruits to curtail the phenomenon.The dietary fibre fractions .......................................
