Diallyl disulfide and the related trisulfide are produced by decomposition of allicin, which is released upon breaking the cells of the Alliaceae plants, especially garlic. The diallyl disulfide yield is the highest for the steam distillation of garlic bulbs which contain about 2 wt.% of diallyl disulfide-rich oil. Diallyl disulfide can also be ...
Whereas the former mechanism acts via skin rubbing which progresses into damage, the major cause of the latter is the chemical diallyl disulfide (DADS), [2] together with related compounds allyl propyl disulfide and allicin. These chemicals occur in oils of plants of the genus Allium, including garlic, onion and leek. [3]
Allicin is unstable and quickly changes into a series of other sulfur-containing compounds such as diallyl disulfide. [3] Allicin is an antifeedant, i.e. the defense mechanism against attacks by pests on the garlic plant. [4] Allicin is an oily, slightly yellow liquid that gives garlic its distinctive odor. It is a thioester of sulfenic acid.
The release is due to the breaking open of the onion cells, which releases enzymes called alliinases. Alliinases then break down amino acid sulfoxides , generating sulfenic acids . A specific sulfenic acid, allicin or 1-propenesulfenic acid, is rapidly rearranged by another enzyme, the lachrymatory factor synthase (LFS) to give syn ...
When crushed and then analyzed using a DART ion source, elephant garlic has been shown to produce both allicin, found in garlic, and syn-propanethial-S-oxide (onion lachrymatory factor), found in onion and leek, but absent in garlic, consistent with the classification of elephant garlic as a closer relative of leek than of garlic.

Allyl propyl disulfide is an organosulfur compound with the chemical formula C 3 H 5 S 2 C 3 H 7. It is a volatile pale-yellow liquid with a strong odor. It is a major component of onion oil and is used in food additives and flavors. [2] Allyl propyl disulfide is present in garlic and onion.
