Objective
Several studies report that the Allium species contain secondary metabolites such as polyphenols, flavonoids and tannins and have bioactivity such as antioxidants, antibacterial, antifungal, anti-inflammatory, pancreatic α-amylase, glucoamylase enzyme inhibitors and antiplatelets. This review summarizes some information regarding the types of Allium species (ethnobotany and ethnopharmacology), the content of compounds of Allium species leaves with various isolation methods, bioactivities, antioxidant properties and the structure-antioxidant activity relationship (SAR) of Allium compounds.
Conclusions
Allium species such as A. cepa, A. sativum, A. fistulosum, A. schoenoprasum, A. ursinum, A. flavum, A. scorodoprasum, A. vineale and A. atroviolaceum have a great role in the health field. Those contain secondary metabolites that have several bioactivities such as antioxidant, antimicrobial, antibacterial, antifungal, anti-inflammatory and others. Their bioactivities are influenced by certain structure and functional groups.
Critical Appraisal
Published research can offer valuable insights, but a paper’s conclusions may go beyond what its results support. Critical appraisal examines the methods, findings and limitations to clarify what can reasonably be concluded—and what remains uncertain.
