Resumo(s)
Project CoHeSus aims to analyze the genetic diversity of cowpea (Vigna unguiculata), as well as its possible contribution to a more sustainable healthy diet, by selecting the varieties most adapted to hot and dry climates and that, at the same time, have a high content of bioactive compounds. Inserted in this project is this systematic review, that has the objective of revising existing literature on the characteristics and possible applications of cowpea extracts.
Cowpea presents a wide range of agronomic and environmental advantages, continuously contributing to the improvement of cropping systems used by subsistence farmers in all of Africa, Asia, and South America. Due to having a low-fat content and being rich in protein, minerals, vitamins and several bioactive compounds (mainly, phenolic compounds and peptides), cowpea is considered to have a high nutritional value.
There have been studies that show that plant extracts rich in peptides and phenolic compounds can display bioactive properties. Since cowpea seed and leaf extracts can also contain high yields of these bioactive compounds, they are expected to have the same properties.
The studies revised here showed that the cowpea extracts’ level of activity was dependent of the used cowpea variety and of the type of extract. In general, the extracts were successful in inhibiting microbial growth, protecting cells and DNA against oxidative stress, inhibiting the expression of proinflammatory proteins, regulating expression of glucose transporters and arresting cancerous’ cell cycles. These features prove the antimicrobial, anti-inflammatory, antidiabetic and anticancer properties of cowpea extracts, with potential to be used as functional food ingredients
