antineoplastic, antibacterial, apoptosis inducer, insecticide

Využitie

Diallyldisulfide has a range of uses varying from a Cytocrome P450 inhibitor to vasorelaxant and hypotensive. Being in the class of organosulfur compounds, it carries chemopreventive characteristics .

Definícia

ChEBI: An organic disulfide where the organic group specified is allyl. It has been isolated from garlic and other species of the genus Allium.

Príprava

By oxidation of allyl mercaptan with iodine in the presence of pyridine and ethanol; from sodium allyl thiosulfate with potassium hydroxide.

Aroma threshold values

Detection: 4.3 to 30 ppb; Recognition: 80 ppb

Taste threshold values

Taste characteristics at 2 ppm: green onion and garlic-like with meaty nuances

Kontaktovať alergény

Diallyldisulfide is one of the major allergens in garlic (Allium sativum) and onions. Among patients patch-testpositive to garlic, all 13 who were tested had positive reactions to diallyl sulfide 5% pet.

Spôsoby čistenia

Purify the disulfide by fractional distillation until the molar refractivity is in uniformly good agreement with the calculated value [Small et al. J Am Chem Soc 69 1710 1947]. It has also been purified by gas chromatography [retention times: Carson & Wong J Org Chem 24 175 1959, UV: Koch J Chem Soc 395 1949]. It is present in garlic. [Beilstein 1 IV 2098.]
