Sur les constituants odorants de l'essence absolue de Cassie (<i>Acacia farnesiana</i> W<scp>ILLD.</scp>)

Abstract

Abstract The absolute oil of cassie ( Acacia farnesiana W ILLD. ) has been thoroughly investigated by using several combined chromatographic techniques. Among the 38 new constituents which were thus identified in this oil, four deserve a particular mention, namely, the cis ‐3‐methyldec‐3‐en‐1‐ol (I), the related acid III, the trans ‐3‐methyl‐dec‐4‐enoic acid (IV), and the homoterpene lactone dihydroactinidiolide (II). With the exception of the last one, these unusual C 11 compounds play a prominent role in the characteristic fragrance of cassie oil.
