Mice given allyl sulfide
had improved long and short-term memory.
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 0.625 mg/ml of oils, respectively.
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.
Functional components in garlic of preventing cardiovascular diseases included allicin, allyl sulfides
, flavonoids, and polysulfides; nevertheless, major functional components in onion of preventing cardiovascular diseases contained quercetin, flavonoids, furostanol saponins, and thiosulfinates.
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.
They also contain phytochemicals, such as quercetin and allyl sulfides
, which are linked to heart health, immune function and anti-cancer effects.
And garlic's allyl sulfides
may confer anti-cancer effects.
Scientists are interested in onions' abundant polyphenol and sulfur-containing compounds, such as quercetin and allyl sulfides
, that may lower the risk of some cancers and help maintain heart health and immune function, reports Zied.
