Abstract
This paper reviewed the beneficial effects of the major phenolic acid compounds of Sorghum bicolor seeds. Different studies were reviewed to determine the major phenolic acid components of sorghum seeds. Several kinds of literature were then analyzed to discuss the different beneficial effects of these molecules. S. bicolor is an important source for food and feed. It is among the top five crops regarding its production and consumption throughout the world. Till date, many studies highlighted different aspects of the biochemical and physiological properties of sorghum grain. However, studies concerning the pharmacological properties of sorghum grain are scarce. The predominant phenolic acids of sorghum seeds are ferulic, p‑coumaric, and protocatechuic acids. The bioactive effects of these phenolic acids are mainly related to their antioxidant, antitumor, antidiabetic, antimicrobial, cardiovascular, and gastrointestinal activities. The data collected from recent studies indicate that these molecules have a promising future as natural agents for the treatment of various diseases, and this is particularly due to their strong antioxidant properties. This review provides evidence for the importance of sorghum seeds and their phenolic compounds in the prevention and treatment of several diseases. This work showed that sorghum grains are a good source of beneficial and therapeutic molecules. It also recommended the addition of sorghum grains to human diet as other cereals because of its high nutritional value.
