Description Allicin and other allyl thiosulphinates possess broad antimicrobial and health-promoting properties, which
makes them natural and safe substitutes for synthetic preservatives. These thiosulphinate compounds were in-
vestigated in 33 Allium accessions representing 14 species, and these species differed significantly in their
content of allicin, allyl methyl thiosulphinates (AMThs), and allyl trans-1-propenyl thiosulphinates (ATPThs) as
ascertained using liquid chromatography tandem mass spectrometry. Total thiosulphinates were the highest in
Allium sativum, Allium guttatum, Allium tuberosum, and Zimmu (an interspecific hybrid of Allium cepa L. and Allium
sativum L.). Allicin and other allyl thiosulphinates content was higher in flat and non-waxy leaves than in fistular
and waxy leaves. Total thiosulphinates content was also significantly higher in cultivated and semi-domesticated
species. Cluster analysis revealed that both foliage type and thiosulphinate content had played a major role in
the clustering. These findings are useful in finding alternative sources of allicin and other thiosulphinates, and
some of the accessions may serve as sources of natural preservatives for application in other research-related or commercial activities.
