For all the investigated onion landraces, quantitative analysis showed that di- and trisulfides, such as cis- and trans-methyl-1-propenyl disulfide, methyl-2-propenyl disulfide, dipropyl disulfide, cis- and trans-propenyl propyl disulfide, methyl propyl trisulfide, and dipropyl trisulfide, were the largest part, whose sum represents about 60% of S-compounds.
