Chemical ConstituentAllium sativum
In 1948, Stoll and Seeback isolated the active principles of garlic in the pure crystalline form called alliin. Alliin is a precursor of a highly bactericidal substance, allicin which is formed by the decomposition of alliin along with pyruvic acid and ammonia in the presence of garlic constitutional enzyme alliinase.
Alliin Allicin + Pyruvic Acid + Ammonia.
Whenever any part of the garlic is damaged, the above reaction occurs and forms allicin which has the characteristic odour of garlic.
Besides this, a number of other antibiotic principles have also been isolated, namely, allistatin I, allistatin II (Datta et al, 1948) and garlicin (Watt and Breyer-Brandwijk, 1962).
