ABSTRACT Stability of allicin in garlic juice was evaluated by gas chromatography (GC) and nonhealing HPLC. Garlic (Allium sativum) is widely distributed and used in all parts of the world.Several clinical reports, including meta-analyses, have described the hypocholesterolemic effect of garlic in humen (Warshafsky et al., 1993; Silagy and Neil, 1994).. Quantitative estimation showed allicin to be 81.37 % in the extract made. Crushed raw garlic is high in allicin, containing ∼3.7 mg/g (Lawson et al. Intraperitoneal injection of aqueous garlic 1, Fig. The health benefits of garlic likely arise from a wide variety of components, possibly working synergistically. Keywords:Allium cepa, Allium sativum, garlic, onion, allicin, organosulfur, flavonoids, sterols. Alliin/Allicin content variations in Garlic. One mol of thiosulphinite reacts with 2 mol cysteine and since allicin makes up 60-80% of the thiosulphinates produced in garlic, multiplying the total thiosulphinate content by a factor of 0.7 gives the approximate allicin content (Curtis et al., 2004). However, garlic powders contain only 1% alliin at most, indicating that more than half of the alliin is lost during dehydration. forming allicin. Study of chemical composition of garlic oil and comparative analysis of co-trimoxazole in response to … Blood pressure was monitored (weekly/6 weeks). reported that ajoene is responsible for most of the biological effects of garlic. J. Garlic had anti-hyperlipidemia ability. It was found that sugars present in the garlic and the high molecular mass of the enzyme were responsible for protection against degradation at high drying temperatures. Allicin is the most predominant thiosulphate in garlic that is garlic, namely alliin, γ-glutamyl and their derivatives [14]. ; Intake of garlic induced the level of TC and LDL. Garlic contains Alliin (S-allyl-l-cysteine sulfoxide) ,Alliin is an amino acid, which converted into Allicin (Di allyl sulphide) in presence of enzyme Alliinase, Allicin produce characteristic smell of garlic while garlic … Many health benefits associated with garlic can be attributed to thiosulfinates, especially allicin [5]. Ajoene has the advantage of a greater chemical stability than allicin . The data is summarized in Table 3.In case of antibacterial activity studies, allicin-rich extract showed comparable diameter of zone of growth inhibition against E. coli, S. aureus and B. subtilis, at concentrations lower than that of the standard drug amoxicillin. Some alarming cases notice that it might help keep a few types of disease as well. 63, 514 (1956). KEY WORDS. Tyagi G, Pradhan S, Srivastava T, et al. There was a linear correlation between the amounts of allicin, flavonoids, or phenolic components derived from fresh, microwaved, 3-month-old, leaves, and boiled garlic and cancer growth prevention. Nucleic acid binding properties of allicin: Spectroscopic analysis and estimation of anti-tumor potential. A few advantages of garlic are credited to the nearness of the sulfur-containing compound, Allicin, found in new, smashed or bit garlic, because of which it has hostile to bacterial and against contagious properties. The absorbance of the collected fraction was measured at 240 nm and 254 nm using a 1 cm quartz cuvette. Wills, E.D. The concentration of allicin in the isolated fraction was standardized by spectrophotometry, according to the HPLC analysis. 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 analysis with UV−vis absorbance detection.
