The quality of garlic and garlic products is usually related to their alliin content and allicin release potential. Until now no analytical method was able to quantify simultaneously allicin, its direct precursor alliin (S-allyl-L-cysteine sulfoxide), SAC (S-allyl-L-cysteine) as well as various
BACKGROUND
Garlic is one of the most important bulb vegetables and is mainly used as a spice or flavoring agent for foods. It is also cultivated for its medicinal properties, attributable to sulfur compounds, of which allicin is the most important. However, the stability of allicin in garlic extract
A quantitative method is described for the determination of allicin (2-propene-1-sulfinothioic acid S-2-propenyl ester) in garlic, using standard additions of alliin (l-(+)-S-allylcysteine sulfoxide) in conjunction with supercritical fluid extraction (SFE) and high performance liquid chromatography
Supercritical fluid chromatography-mass spectrometry has been used successfully to identify allicin (2-propene-1-sulfinothioic acid S-2-propenyl ester), the predominant thiosulfinate in freshly cut garlic (Allium sativum). A low oven temperature (50 degrees C) and low restrictor tip temperature (115
OBJECTIVE
To identify studies measuring garlic powder tablets effects on systolic and diastolic blood pressure and to investigate if studies published prior to January 1994 would perform better than those published later.
METHODS
Using MEDLINE (January 1966 through December 2004) studies involving
OBJECTIVE
The evaluation of allicin, the biologically active compound responsible for the antimicrobial activities of freshly crushed garlic cloves, in inhibiting Aspergillus spp. in vitro and in a murine model of disseminated aspergillosis.
METHODS
Pure allicin was prepared by reacting synthetic
Pneumolysin (PLY) is a key virulence factor contributes to the pathogenesis of Streptococcus pneumoniae. In this study we investigated the effect of allicin and aqueous garlic extracts on hemolytic activity of PLY both in prelysed and intact cells. Additionally the antimicrobial activity of allicin
The OOH radical reactions with allicin and its Cope elimination products (2-propenesulfenic acid and thioacrolein) in aqueous solution have been studied. The CBS-QB3 quantum chemistry method has been used, with geometries and frequencies at BHandHLYP/6-311++G(d,p) level and conventional transition
To analyze the chemical components and decomposition products in allicin extract of garlic, the chemical components screening and identification were made with HPLC-MS/MS method by full scan TIC MS, HPLC retention time, product MS spectra and chemical reference standards. The stability of the
A cationic antibacterial peptide, polymyxin B (PMB), was evaluated as an antifungal antibiotic against various yeasts and filamentous fungi when used in combination with allicin, an allyl sulfur compound from garlic. Allicin was not lethal but could markedly amplify the fungicidal activity of PMB,
OBJECTIVE
Allicin is believed to be the main component responsible for the biological activity of garlic. The regulation of cell death might have therapeutic potential in many diseases, and previous studies have demonstrated that allicin stimulates the functional activity of macrophages. Therefore,
Amphotericin B (AmB) is a representative antibiotic for the control of serious fungal infections, and its fungicidal activity was greatly enhanced by allicin, an allyl-sulfur compound from garlic. In addition to the plasma membrane permeability change, AmB induced vacuole membrane damage so that the
OBJECTIVE
Allicin is believed to be the main component responsible for the biological activity of garlic. The regulation of cell apoptosis may have therapeutic potential for trauma/hemorrhagic shock, and previous studies have demonstrated that allicin exerts protective effects against tissue
Allicin, diallyl disulfide-oxide, an active ingredient released from garlic is a systemic vasodilator that acts by an unknown mechanism. In the present experiments, pulmonary vascular responses to allicin (0.1-1.0 mg) were studied in the intact-chest anesthetized cat and in the isolated lung of the
OBJECTIVE
Trichophyton rubrum (T. rubrum) is one of the most common dermatophytes worldwide. This fungus invaded skin appendages of humans and animals. Recently, resistance to antifungal drugs as well as appearance of side effects due to indication of these kinds of antibiotics has been reported.
