-The major part of the absolute (more than 230 compounds) consisted of fatty acids and their esters (ethyl-, 2-methylbutyl-, benzyl- and phenylethyl-). Other components were benzyl cyanide (4.75%), 2-phenylnitroethane (1.10%), isoeugenol (0.45%), aliphatic nitriles, phenols and lilac alcohols. \\+The major part of the absolute (more than 230 compounds) consisted of fatty acids and their esters (ethyl-, 2-methylbutyl-, benzyl- and phenylethyl-).
