Phytochemical and bioactive potentials of African Annonaceae species
Publication . Rangel, Josefa; Liberal, Ângela; Catarino, Sílvia; Costa, José Carlos; Romeiras, Maria M.; Fernandes, Ângela
This review aims to gather available information on the medicinal, nutritional, and bioactive profiles of Annonaceae species in the African continent, sponsoring their use worldwide and mainly in African communities, where access to food and medicines for basic health care is scarce. >60 medicinal taxa were compiled, belonging to 22 genera, namely Annickia, Annona, Anonidium, Artabotrys, Cleistochlamys, Cleistopholis, Dennettia, Duguetia, Greenwayodendron, Hexalobus, Isolona, Lettowianthus, Monanthotaxis, Monodora, Neostenanthera, Polyceratocarpus, Sphaerocoryne, Uvaria, Uvariastrum, Uvariodendron, Uvariopsis and Xylopia; the most diverse and economically important genera were the genera Annona, Uvaria and Xylopia with 7 species each. Annonaceae species hold a valuable nutritional profile, rich in proteins, fibers, and minerals, being also good sources of a wide range of bioactive compounds of high biological relevance. These compounds are especially important in developing countries, where most of these species are available for direct use as food and/or medicines by the most deprived populations.
Valorization of Waste from Bell Pepper: Chemical Composition and Bioactive Potential

Agri-food waste, especially in the fruit and vegetable sector, presents environmental and economic challenges. The bell pepper industry generates significant waste, offering potential for resource recovery within a circular economy. This study analyzed the nutritional and biochemical composition of waste from green, orange, and red bell peppers (Capsicum annuum L.) and evaluated the bioactive potential of hydroethanolic extracts from fruits, stalks, and seeds. Carbohydrates were the main macronutrients, followed by proteins and ashes. Fructose was dominant in orange and red peppers, while glucose prevailed in green peppers. Waste samples contained organic acids, fatty acids, and phenolic compounds, including oxalic and malic acids, polyunsaturated fatty acids, 22 bioactive phenolics, and 34 volatile compounds. Hydroethanolic extracts demonstrated strong antioxidant activity, with green bell pepper waste showing the highest levels. The extracts also exhibited antibacterial effects against Yersinia enterocolitica and Bacillus cereus and antifungal activity against Aspergillus brasiliensis. These findings highlight the potential of bell pepper waste as a rich source of bioactive compounds with applications in food, cosmetics, and pharmaceuticals. Utilizing these by-products promotes sustainability, supports the circular economy, and addresses global waste challenges.
