- Compositional features and biological activities of wild and commercial Moringa oleifera leaves from Guinea-BissauPublication . Fernandes, Ângela; Liberal, Ângela; Pinela, José; Finimundy, Tiane C.; Bancessi, Aducabe; Ćirić, Ana; Soković, Marina; Catarino, Luís; Ferreira, Isabel C.F.R.; Barros, LillianMoringa oleifera Lam. is a nutraceutical edible plant used to fight malnutrition in developing countries. This investigation describes the nutritional, chemical and bioactive assets of wild and commercially acquired M. oleifera leaves from Guinea-Bissau. Both samples presented significant differences in the contents of almost all the analysed parameters. Carbohydrates and proteins were the major constituents of the leaves, which also showed an interesting profile of tocopherols, organic acids, unsaturated fatty acids, and phenolic compounds. The infused extract of the commercial leaf sample was more effective than other preparations against lipid peroxidation and oxidative haemolysis. In turn, higher antibacterial activity was achieved with hydroethanolic and infused extracts of the wild sample, which extracts also displayed superior antifungal activity. Overall, the commercially acquired M. oleifera leaves stand out with better quality profiles than the wild collected, which aroused interest in studying the processing methods used locally to process this functional food.
- Nutritional and phytochemical profiles and biological activities of Moringa oleifera Lam. edible parts from Guinea-Bissau (West Africa)Publication . Fernandes, Ângela; Bancessi, Aducabe; Pinela, José; Dias, Maria Inês; Liberal, Ângela; Calhelha, Ricardo C.; Ćirić, Ana; Soković, Marina; Catarino, Luís; Ferreira, Isabel C.F.R.; Barros, LillianMoringa oleifera is an edible medicinal plant used to fight malnutrition in Africa. In this study, M. oleifera flowers, fruits and seeds from Guinea-Bissau were characterized for their nutritional composition and hydroethanolic and aqueous extracts were prepared to investigate the phenolic profiles and bioactivities. Seeds presented higher levels of proteins (~31 g/100 g dw), fat (~26 g/100 g dw) and flavan-3-ol derivatives, while carbohydrates, proteins, citric acid, and glycosylated flavonoids were abundant in fruits and flowers, these last samples also being rich in α-tocopherol (~18 mg/100 g dw). Some of the identified polyphenols had never been described in M. oleifera. In general, hydroethanolic extracts contained more polyphenols and were more active against lipid peroxidation, NO production, and tumour cells growth. Significant antimicrobial effects against the tested bacteria and fungi strains were displayed by both hydroethanolic and aqueous extracts. The M. oleifera potential to fight malnutrition and health issues was highlighted.
