Online ahead of print. 2019;12:425–434. In the typical serving size of 1–3 cloves (3–9 grams), garlic provides no significant nutritional value, with the content of all essential nutrients below 10% of the Daily Value (DV) (table). These sulfoxides, except cyloalliin, are converted into thiosulfinates (such as allicin) through enzyme reactions when raw garlic is cut or crushed. Allicin, the major organosulfur compound is very unstable. -. Bioactive properties are attributed to the organosulfur compounds content. Medicinal plants have been used from ancient times for human healthcare as in the form of traditional medicines, spices, and other food components. Ticks Tick Borne Dis. A. sativum is rich in several sulfur-containing phytoconstituents such as alliin, allicin, ajoenes, vinyldithiins, and flavonoids such as quercetin. The anticandidal activities of commercially available garlic supplement products corresponded in general to the activities known for the chemical compounds found in the products. This chapter focuses on the heterogeneous composition of the essential oils. Garlic contains at least 33 sulfur compounds like aliin, allicin, ajoene, allylpropl, diallyl, trisulfide, sallylcysteine, vinyldithiines, S-allylmercaptocystein, and others. Antioxidants (Basel). The major sulfur-containing compounds in intact garlic are γ-glutamyl-S-allyl-L-cysteines and S-allyl-L-cysteine sulfoxides (alliin). Garlic cloves are sliced or crushed, dried and pulverized into powder. An odor or odour is a volatile chemical compound that humans and other animals perceive via the sense of smell or olfaction. Chemical compounds studied in this article: (E)-ajoene (CID 5386591); (Z)-ajoene (CID 9881148); allicin (CID 65036); alliin (CID 87310); allixin (CID 86374); γ- 1991 Aug;57(4):371-5. doi: 10.1055/s-2006-960120. chemical composition of garlic essential oil was also determined and primary compounds were dimethyl trisulfide (19.86%), diallyl disulfide (18.62%), diallyl sulfide (12.67%), diallyl tetrasulfide (11.34%), and 3-vinyl-[4H]-1,2-dithiin (10.11%). Thus allyl sulfides are characteristics of oil of garlic, traces of indole and anthranilic acid esters are found in orange oil, straight chain alcohols and aldehydes are recognized in oil of violets, and phenols and other aromatic compounds are common to many oils. 1 ).
