Background: There is an increasing interest from the pharmaceutical and food industry in natural
antioxidant and bioactive compounds derived from plants as substitutes for synthetic compounds. The genus
Allium is one of the largest genera, with more than 900 species, including important cultivated and wild species,
having beneficial health effects.
Objective: The present review aims to unravel the chemical composition of wild Allium species and their healthrelated
effects, focusing on the main antioxidant compounds. For this purpose, a thorough study of the literature
was carried out to compile reports related to health effects and the principal bioactive compounds. Considering
the vast number of species, this review is divided into subsections where the most studied species are presented,
namely Allium ampeloprasum, A. flavum, A. hookeri, A. jesdianum, A. neapolitanum, A. roseum, A. stipitatum, A.
tricoccum, and A. ursinum, with an additional composite section for less studied species.
Methods: The information presented in this review was obtained from worldwide accepted databases such as
Scopus, ScienceDirect, PubMed, Google Scholar and Researchgate, using as keywords the respective names of
the studied species (both common and Latin names) and the additional terms of & quot; antioxidants & quot; &
quot; health effects & quot; and & quot; bioactive properties & quot.
Conclusion: The genus Allium includes several wild species, many of which are commonly used in traditional
and folklore medicine while others are lesser known or are of regional interest. These species can be used as
sources of natural bioactive compounds with remarkable health benefits. Several studies have reported these
effects and confirmed the mechanisms of action in several cases, although more research is needed in this field.
Moreover, considering that most of the studies refer to the results obtained from species collected in the wild
under uncontrolled conditions, further research is needed to elucidate the effects of growing conditions on bioactive
compounds and to promote the exploitation of this invaluable genetic material.
