Abstract
N-Propylthiol was detected in the onion, and characterized as the mercuric, lead and silver salts. The thiol was removed from the freshly chopped bulbs in a stream of sterile air and absorbed in mercuric cyanide. The behavior of diallyl disulfide, the main constituent of oil of garlic, Allium sativum. was investigated in cultures of the mold Scopulariopsis brevicaulis which convert it to methyl allyl sulfide and allyl sulfide and allylthiol. These compounds were identified as the platinichloride and the mercuric, lead and silver salts respectively.
