AI Article Synopsis

  • Samh flour, derived from Mesembryanthemum forsskalei, serves as a high-protein alternative to wheat flour and is traditionally consumed by Bedouin tribes in northern Saudi Arabia.
  • Researchers identified 43 secondary metabolites in the flour using advanced techniques, categorizing them into five main groups including flavonoids and glucosinolates.
  • The study found that compounds in samh flour have significant antioxidant properties, helping to reduce oxidative damage to proteins and lipids in human plasma.

Article Abstract

Samh flour (Mesembryanthemum forsskalei) is a foodstuff with high protein content, which can be used as a replacement for wheat flour. It is often consumed by Bedouin tribes of northern Saudi Arabia. Very little is known about bioactive molecules present in samh flour, therefore we analyzed its extracts to evaluate the contents of secondary metabolites. A total of 43 secondary metabolites present in 60% MeOH extract of samh flour were tentatively identified using LC-ESI-MS/MS. These compounds represented five major categories: glucosinolates, sinapic acid and sinapoylglycosides, acylated flavonoids, flavonoids, and amide derivatives. Their effect on oxidative damage of proteins and lipids was determined in vitro by assessing levels of protein thiol groups and concentrations of thiobarbituric acid reactive species (TBARS) in human plasma. Obtained results indicated that samh flour is a rich source of compounds with antioxidant activity.
