+The headspace of S.niger flowers contained 5-hydroxylinalool (6.4%, odor type floral-sour citrus, with a dry straw undertone), furthermore [[http://www.thegoodscentscompany.com/data/rw1624501.html|isoleucine methyl ester]] (7%) and also valine methyl ester (0.3%). In particular methyl isoleucinate contributes to the special odor of the fresh flowers. Literature-mentioned amines like ethylamine, isobutylamine and isoamylamine could not be found, but imines derived from isoleucine methyl ester with acetaldehyde (0.15%), butanal (0.1%), and acetone (0.15%), definitely identified with authentic samples and GC. \\

 The fruity group consisted of aliphatic alcohols and aldehydes and aromatic esters, of which 1-pentanal, 2-methyl-1-propanol, 2- and 3-methyl-1-butanol, 1-octanal, 1-octanol and methyl and ethyl benzoate contributed with fruity notes. In the flowery group, 1-nonanal, nerol oxide and (Z)- and (E)-rose oxide contributed with characteristic elder flower odour, whereas other flowery notes were associated with hotrienol, linalool and α-terpineol. Fresh and grassy odours were correlated with 1-hexanal, (E)-2-hexen-1-al, (Z)-3-hexen-1-ol, (E)-2-hexen-1-ol and (E)-2-octen-1-al of the grassy group, whereas 1-octen-3-ol and 1-octen-3-one of the agrestic group contributed significantly with the characteristic aroma of mushrooms." \\
