Chemotypes main groups 129

The spectrum of these monoterpenes is very wide. There are representatives of each type of the basic monoterpene skeletons except the carane group. Even if the main component itself is usually not enough for evaluation of the characteristics of the oil, tansy is a good example to illustrate the fact that the main compounds of different chemotypes may not necessarily belong to the same skeleton. It also means that they are not always products of closely related biosynthetic pathways, which might re ect a really heterogeneous genetic structure.
