"The flavour composition of dried flowers of Manzanilla de la Montaña (Helenium aromaticum syn. Cephalophora aromatica) was investigated by means of gaschromatography-mass spectrometry (GC-MS). The essential oil content was 0.55 ml/100g containing up to 80% esters, mainly of methyl-branched alcohols (methylbutanols, 3-methylbut-2-en-1-ol, 3-methylbut-3-en-1-ol, (E) and (Z)-2-methylbut-2-ene-1,4-diol, acyclic terpenols) with acetic and short-chain methyl-branched acids. The typical fruity flavour of this compositae can be attributed to [[http://www.thegoodscentscompany.com/data/rw1004871.html|ethyl 2-methylbutanoate]] and its homologes. Additionally, the ether extract of the flowers contains sesquiterpene lactones, tentatively identified as helenanolides. These pseudoguaianolides are of toxicological and pharmacological interest, especially because of their cytotoxic and antitumour activities." \\

"Hydrodistilled volatile oil from the flowers of Cephalophora aromatica Schrad. (cultivated in Iran) was analysed by a combination of GC and GC–MS. Twenty-nine components were identified. The main constituents of the essential oil were 2-ethyl hexanoic acid (27.0%), n-undecane (14.1%), decane (11.4%) and geranyl tiglate (7.9%)." \\
