axilla of the subject, of at least one compound selected from the group of compounds consisting of:
octanal; 1-tetradecanol; 1,3-
butanediol; 1-hexadecanol;
hexanoic acid; dodecanal; propionic acid; 2,6,10,14-tetramethyl-
pentadecane;
heptadecane; 1-pentadecanol; (Z)-9-
octadecenoic acid; 1-
dodecanol, 1-
octanol; hexahydro-2H-azepin-2-one; 1-tridecanol;
tetradecane;
octadecane; tetradecanoic acid; (E)-geranylacetone; (Z)-9-hexadecenoic acid;
hydrogen sulfide; and 2-pyrrolidone.
