The Allium oil fractions, allicin, allyl sulfide, and ally disulfide were serially diluted with 10% dimethyl sulfoxide (DMSO) and added with 10 [micro]l of Tween 80 to prepare the solutions, which contained from 160 to 0.
We compared the activities of the volatile oils of Allium species with allicin and with diallyl sulfide and allyl sulfide, which are the expected decomposition products of allicin.
Onions, garlic and leek contain allyl sulfides
and are associated with lowering cholesterol, blood pressure and cancer risk.
Or allyl sulfides
, dithiolthiones, or isothiocyanates?
increase the production of glutathione S-transferase, which may make carcinogens easier to excrete.
