 chemosystematic studies.... The most important compounds for the aroma of the oils (Latrasse et al., 1982; Latrasse, 1983) were present in the polar fractions, even though they were found in very small amounts. Thus, the sulfur compound 4-methoxy-2-methyl-2-mercaptobutane responsible for the characteristic catty note was found in small amounts varying from trace to 0.04%, the highest level, however, being found in aromatic varieties (eg Noir de Bourgogne, Burga, Royal de Naples). Concentration of eucalyptol (1,8-cineole), important for its characteristic balsamic note, varied from trace to 0.01% of the total oils, and 1-octen-3-ol, with its mushroom odor, was only found in trace amount. More abundant in these polar fractions, monoterpene alcohols, such as linalool or citronellol, generally give off typical floral notes, while sesquiterpene alcohols and oxides, such as spathulenol, caryophyllene oxide, or isospathulenol, afford conifer like odors. Monoterpene acetates have been found particularly important for their characteristic floral or lemony notes." \\ chemosystematic studies....

 +"The first use of the 'Bourgeons de Cassis' note in a prominent perfume was certainly Amazone (Hermes 1974), and that set the fashion. Silences (Jacomo-1978) followed, together with many others. The absolute harmonizes well with green floral notes while accentuating its own characteristics and bringing out its fruity side. Its use has been restricted because of cost, and perfumers have turned to the essential oil of buchu, which unfortunately does not possess all the qualities of the 'Bourgeons de Cassis' absolute." \\
