Abstract
Application of aroma extract dilution analysis on an extract of the dried f ruits of the West African peppertree Xylopia aethiopica obtained by extract ion with diethyl ether followed by sublimation in vacuo revealed 28 odor-ac tive compounds in the flavor dilution (FD) factor range of 4-8192, all of w hich could be identified. The highest FD factor was found for linalol (flor al), followed by (E)-beta-ocimene (flowery), alpha-farnesene (sweet, flower y), beta-pinene (terpeny), alpha-pinene (pine needle-like), myrtenol (flowe ry), and beta-phellandrene (terpeny). Vanillin (vanilla-like) and 3-ethylph enol (smoky, phenolic) showing somewhat lower FD factors (FD = 128) were de tected for the first time as constituents of the dried fruit.
