New components in defensive secretion of the striped skunk,Mephitis mephitis.

GC-MS analysis of the anal sac secretion of the striped skunk (Mephitis mephitis), shows seven major components: (E)-2-butene-1-thiol, 3-methyl-1-butanethiol, S-(E)-2-butenyl thioacetate,S-3-methylbutanyl thioacetate, 2-methylquinoline, 2-quinolinemethanethiol, andS-2-quinolinemethyl thioacetate. The following compounds previously reported from this secretion could not be confirmed: bis(2-butenyl) sulfide, (E)-2-Butenyl methyl disuffide, (E)-2-butenyl propyl sulfide, butyl 3-methylbutyl disulfide, and 2-butenyl butyl disulfide.
