Beschreibung
Diallyl disulfide is one of the major allergens in garlic
(Al/ium sativum) and onions. Among patients who are
patch-test positive to garlic, all 13 who were tested had
positive reactions to diallyl sulfide 5% petrolatum.
Chemische Eigenschaften
CLEAR YELLOW LIQUID
Occurrence
Main constituent of Allium sativum essential oil. Reported found in onion (Allium cipa, L.), garlic (Allium
sativum L.), chive (Allium schoenoprasum L.), nira (Allium tuberosum rottl.), raw cabbage and caucas (Allium victoralis L.).
Verwenden
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 .
synthetische
By oxidation of allyl mercaptan with iodine in the presence of pyridine and ethanol; from sodium allyl thiosulfate with
potassium hydroxide.
Definition
ChEBI: An organic disulfide where the organic group specified is allyl. It has been isolated from garlic and other species of the genus Allium.
Allgemeine Beschreibung
Allyl disulfide is naturally found in Allium species such as garlic and onion. It is used as a flavoring agent in meat and condiments.
Kontakt-Allergie
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.
läuterung methode
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.]
