Chemical
Constituent
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).
