The identification of two new natural products, (E)-4,8-dimethyl-1,3,7-nonatriene 1 and (E,E)-4,8,12-trimethyl-1,3,7,11-tridecatetraene 3 is reported. These unusual C11 and C16 hydrocarbons were isolated from the essential oil of Elettaria cardamomum Maton var. miniscula Burkhill (Zingiberaceae) and their structures confirmed by synthesis.

ZusammenfassungMehrere in der Aromenindustrie häufig verwendete Ester konnten jetzt erstmals in natürlichen Aromen nachgewiesen werden. Folgende Verbindungen wurden durch GC/MS identifiziert (in Klammern die natürliche Quelle): (E)-Cinnamylformiat (Zimt), (E)-Cinnamylpropionat (Zimt), (E)-Cinnamylisobutyrat (Zimt), (E)-Isobutylcinnamat (Zimt, Styrax), (E)-Isopentylcinnamat (Zimt, Styrax), (E)-2-Methylbutyl-cinnamat (Zimt, Styrax), Isobutylphenyl-acetat (Kakao) und 1-Phenylethyl-isobutyrat (Rum).SummarySeveral esters routinely used by the flavour industry have been detected for the first time in natural flavours. The following compounds were identified by GC/MS (the natural source in parentheses): (E) cinnamyl formate (cinnamon), (E)-cinnamyl propionate (cinnamon), (E)-cinnamyl isobutyrate (cinnamon), isobutyl (E)-cinnamate (cinnamon, styrax), isopentyl (E)-cinnamate (cinnamon, styrax), 2-methylbutyl (E)-cinnamate (cinnamon, styrax), isobutyl phenylacetate (cacao), and 1-phenylethyl isobutyrate (rum).Mehrere in der Aromenindustrie haufig verwendete Ester konnten jetzt erstmals in naturlichen Aromen nachgewiesen werden.
