A method is described for determining sulfite in dried garlic. Garlic is extracted with an HCl solution to inhibit the formation of allicin, which interferes with the determination of sulfite. After cleanup of the extract on a C18 solid-phase extraction column, sulfite is converted to hydroxymethylsulfonate (HMS) by adding formaldehyde and heating to 50 degrees C. HMS is determined by reversed-...

Aims: The aims of this work were to quantify allicin an abundant antioxidant in different aqueous garlic extract samples and to determine the stability of allicin in the extract under different thermal and solvation conditions. Study Design: Descriptive research. Place and Duration of Study: Department of Chemistry and Biochemistry and Department of Biological Sciences, California State Polytec...

This study investigated the effects of garlic oil (0.25 g/L), nitrate (5 mM), and quillaja saponin (0.6 g/L), alone and in binary or ternary combinations, on methanogenesis, rumen fermentation, and abundances of select microbial populations using in vitro rumen cultures. Potential adaptation to these compounds was also examined by repeated transfers of the cultures on alternate days until day 1...

There are numerous herbs growing in India, some are cultivated and others are growing wild, among these herbs is well known name Garlic (Allium sativum L.) which is cultivated and consumed almost across the globe. People use Garlic as a spice / pickles. Garlic contains medicinally active compounds like Alliin/Allicin, Di-allyl Disulfide, 2-vinyl-4H-1, 3-dithiin, Ajoene. Alliin /Allicin is chole...

Allyl sulfur compounds are the major active constituents found in crushed garlic. Research has revealed that garlic and its lipid- or water-soluble components have many pharmacologic properties; however, studies also demonstrate that heating has a negative influence on these beneficial effects. We recently conducted several studies to investigate the influence of microwave or oven heating on th...

Levels of red cell, serum acid, and alkaline phosphatases, serum amylase, alanine and aspartate transferase and bilirubin were examined in streptozotocin-induced diabetic rats treated with garlic oil and compared with the corresponding levels in diabetic control rats, normal rats and normal rats on garlic oil. Values of tissue amylase and total protein were also assessed from the pancreas, live...

Spices like turmeric, ginger, alliums are indispensable for the preparation of our daily food and are reported to possess compounds, which have varied beneficial biological effects and also prevent the microbial spoilage of food. This study evaluates the antioxidant and antimicrobial activity of spice extracts such as ginger, turmeric and garlic by 2, 2’-Diphenyl-1-picrylhydrazyl (DPPH) Radical...

Garlic's pungent flavor has made it a popular ingredient in cuisines around the world and throughout history. Garlic's health benefits have been elevated from folklore to clinical study. Although there is some controversy as to the efficacy of garlic, garlic products are one of the most popular herbal supplements in the U.S. Chemically complex, garlic contains different assortments of sulfur co...

Onion and garlic are best known for their pungent aromas, but these potent veggies have powerful effects on health and also there is urgent need to identify superior populations, quickly characterize and select elite candidates and breed new varieties for achieving current as well as future food and global health security needs. Hence this review article is focused on the analysis of the biolog...

I thought garlic would be a simple, herb-with-some-data-alot-of-hype-some hope-subject for an article. Fat chance. It seems a basic premise was remiss. Until recently most people were convinced that allicin, a sulfur-containing constituent of crushed garlic, was responsible for garlic’s health effects. Manufacturers standardize their garlic supplements according to the percent allicin. Scientis...
