- Valorization of angolan native plants: Nutritional composition, phenolic profile and bioactive potential of Commelina africana, Dombeya rotundifolia and Lablab purpureus leavesPublication . Bastos, Claudete; Liberal, Ângela; Silveira, Tayse F. F. da; Ferreira, Isabel C.F.R.; Pereira, Carla; Pires, Tânia C.S.P.; Mandim, Filipa; Moldão, Margarida; Catarino, Luís; Barros, LillianCommelina africana L., Dombeya rotundifolia (Hochst.) Planch. and Lablab purpureus (L.) Sweet are wild edible plants (WEPs) native to Africa, traditionally used in rural Angolan communities. This study characterizes their nutritional, chemical, and bioactive properties, with carbohydrates and proteins predominating as macronutrients across all species. Monounsaturated and polyunsaturated fatty acids were most abundant in D. rotundifolia and C. africana. Phenolic profiling revealed that C. africana was mainly characterized by p-coumaroyl malic acid and caffeoyl shikimic acid, whereas D. rotundifolia contained majorly flavan-3-ols, including epicatechin and B-type procyanidin oligomers. In contrast, L. purpureus exhibited the highest total phenolic content overall. The hydroethanolic extract of D. rotundifolia exhibited the highest efficacy against foodborne and clinical bacteria and inhibition of cancer cell proliferation. This integrated characterization demonstrates that these underutilized WEPs offer substantial dual nutritional and bioactive value, supporting their traditional use and potential for nutraceuticals and food applications.
- Wild Edible Plants in Angola: Diversity, Traditional Uses, Phytochemical Properties, and Socio‐Economic PotentialPublication . Bastos, Claudete; Liberal, Ângela; Moldão, Margarida; Barros, Lillian; Catarino, LuísWith almost 7000 native species, Angola is one of the African countries with the most remarkable plant diversity. Rural communities use many wild plants daily to fulfill various needs, particularly as food. This study aimed to explore the diversity and uses of wild edible plants (WEP) in Angola, through a literature review, consultation of herbarium collections, and fieldwork by the first author. Through an analysis of databases, books, and scientific articles, and consulting herbarium records, it was possible to identify 199 WEP used in Angola. The main types of plants with edible parts were trees, annual and perennial herbs, shrubs and sub-shrubs, and, to a lesser extent, lianas and herbaceous vines, which are found in forests, woodlands, riverbanks, and gallery forests, as well as in fallows and disturbed places. The most consumed parts of plants are fruits, seeds, leaves, and, to a lesser extent, the underground parts. Many of these plants have great economic value, serving as both food sources and additional income for rural families. The identification and characterization of WEP has enabled a deeper understanding of the country's plant genetic resources, which can help improve food security and promote the sustainable use of natural resources in Angola.
