Antioxidant and Hypolipidemic Potential of Aged Garlic Extract and Its Constituent, S-Allyl Cysteine, in Rats
Aged garlic extract (AGE) is one of the unique preparations standardized with 100% bioavailable active ingredients found in the bloodstream. The current research was aimed at exploring the role of AGE and its chief active constituent, s-allyl cysteine (SAC) as antioxidant and hypolipidemic agent in rats. At the end of treatment of AGE and SAC, separated serum and freshly prepared liver tissue h...
متن کاملThe antioxidant properties of garlic compounds: allyl cysteine, alliin, allicin, and allyl disulfide.
Garlic and garlic extracts, through their antioxidant activities, have been reported to provide protection against free radical damage in the body. This study investigated antioxidant properties of garlic compounds representing the four main chemical classes, alliin, allyl cysteine, allyl disulfide, and allicin, prepared by chemical synthesis or purification. Alliin scavenged superoxide, while ...
متن کاملMetabolism, excretion, and pharmacokinetics of S-allyl-L-cysteine in rats and dogs.
The metabolism, excretion, and pharmacokinetics of S-allyl-l-cysteine (SAC), an active key component of garlic supplements, were examined in rats and dogs. A single dose of SAC was administered orally or i.v. to rats (5 mg/kg) and dogs (2 mg/kg). SAC was well absorbed (bioavailability >90%) and its four metabolites-N-acetyl-S-allyl-l-cysteine (NAc-SAC), N-acetyl-S-allyl-l-cysteine sulfoxide (NA...
متن کاملChemical and Biological Properties of S-1-Propenyl-l-Cysteine in Aged Garlic Extract.
S-1-Propenyl-l-cysteine (S1PC) is a stereoisomer of S-1-Propenyl-l-cysteine (SAC), an important sulfur-containing amino acid that plays a role for the beneficial pharmacological effects of aged garlic extract (AGE). The existence of S1PC in garlic preparations has been known since the 1960's. However, there was no report regarding the biological and/or pharmacological activity of S1PC until 201...
متن کاملSynergistic antiyeast activity of garlic oil and allyl alcohol derived from alliin in garlic.
Garlic oil (GO) and allyl alcohol (AA), both derived from alliin in garlic using different preparation methods, cause potent growth inhibition in yeasts. GO and AA inhibited Candida utilis ATCC42416 in different ways: GO has fungistatic activity while AA has fungicidal activity. GO and AA have almost identical antimicrobial potencies against the indicator yeast, with minimum inhibitory concentr...
