title: The lachrymatory principle of Petiveria alliacea.
abstract: The lachrymatory principle of Petiveria alliacea has been isolated from a fresh homogenate of the root. Its structure and geometric configuration have been determined as (Z)-thiobenzaldehyde S-oxide by means of NMR, IR, MALDI-MS and by comparison with an authentic compound obtained by synthesis. This unique compound represents only the third naturally occurring sulfine (thiocarbonyl S-oxide) to be reported. Its formation and possible subsequent rearrangements are discussed. Its antibacterial and antifungal activities are also reported.
