Garlic (Allium sativum L.) is an aromatic herbaceous plant that is consumed worldwide as food and traditional remedy for various diseases. When fresh garlic is chopped or crushed, the enzyme alliinase converts alliin into allicin, which is responsible for the aroma of fresh garlic. COVID-19: Is There Evidence for the Use of Herbal Medicines as Adjuvant Symptomatic Therapy? • Allicin, the major organosulfur compound is very unstable. Garlic and elephant garlic clove homogenates demonstrated similar activity. 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). The major sulfur-containing compounds in intact garlic are γ-glutamyl-S-allyl-L-cysteines and S-allyl-L-cysteine sulfoxides (alliin). doi: 10.1016/j.jep.2005.04.025.

Per 100 gram serving, garlic is also a moderate source (10–19% DV) of certain B vitamins, including thiamin and pantothenic acid, as well as t… Both are abundant as sulfur compounds, and alliin is the primary odorless, sulfur-containing amino acid, a precursor of allicin (12), methiin, (+)-S-(trans-1-propenyl)-L-cysteine sulfoxide, and cycloalliin (13). Bioactive properties are attributed to the organosulfur compounds content. Garlic considered one of the richest vegetable sources of total phenolic compounds. 2020 Oct 15;8(10):423. doi: 10.3390/biomedicines8100423. -. Garlic contains at least 33 sulfur compounds like aliin, allicin, ajoene, allylpropl, diallyl, trisulfide, sallylcysteine, vinyldithiines, S-allylmercaptocystein, and others. Furthermore, it has also been proposed as one of the richest sources of total phenolic compounds, among the usually consumed vegetables, and has been highly ranked regarding its contribution of phenolic compounds to human diet. https://doi.org/10.1016/j.foodchem.2016.05.029. Garlic essential oil … When expressed per 100 grams, garlic contains several nutrients in rich amounts (20% or more of the DV), including vitamins B6 and C, and the dietary minerals manganese and phosphorus. Garlic contains the highest sulfur content of any member of the genus Allium.
