+The flowers contain bitter sesquiterpene lactones (0.3-1.0%), consisting mainly of esters of helenalin and 11,13-dihydrohelenalin with short-chain fatty acids such as acetic, isobutyric, isovaleric, methacrylic and
+tiglic acids. Two chemotypes are distinguished: The helenalin type is native to Central Europe and the dihydrohelenalin type (which contains only traces of helenalin) is native to Spain. Essential oil (0.2-0.35%) present consists mainly (40-50%) of fatty acids. \\
