✦ Synopsis
Forty-three sulphurcontaining constituents were found in a pentane extract of the durian fruit (Durio zibethinus Murr., Bombacaceae). Amongst them, 22 are new compounds. They belong to dialkyl di-and trisulphides, 3-(alkylthi0)-and 3-(alkyldithio)-butan-l-ols, 1,l-bis(a1kylthio)alkanes and 1-(alkylthi0)-1-(alkyldithio)alkanes, trithiolanes, tetrathiolanes and S-alkyl thioesters. In addition, the ethyl (Z,Z)- , (E,Z)and(E,E)-deca-2,4dienoates, ethyl (3Z,6Z)-decadienoate and the ethyl (E,Z,Z)and(E,E,Z)-decatrienoates contribute significantly to the fruity aspect of the unusual flavour. Some olfactive evaluations of the synthesised constituents are described.
