Achillea filipendulina

Cyclopentane bicyclic monoterpenoids that occur in the plant kingdom belong to three major skeletal types camphane, iso-camphane, and fenchane (Fig. 7). Camphane-type terpenoid alcohols, (+)-bomeol (Gl) and (—)-isobomeol (G2), have been isolated from Cinnamomum camphora (Lauraceae) and Achillea filipendulina (Asteraceae). A ketone derived from these, (-h)-camphor (G3), is found in the camphor tree Cinnamomum camphora) and in the leaves of rosemary Rosmarinus officinalis) and sage Salvia officinalis, Labiatae). Camphene (G4) and its enantiomer with the isocamphane carbon skeleton are known to occur in the oils of citronella and turpentine. Fenchane-type bicyclic cyclopentane monoterpenoids are commonly found in plants as their ketone derivatives. (—)-Fenchone (G5) occurs in the tree of life Thuja occidentalis, Cupres-saceae). Its enantiomer, (+)-fenchone (G6), has been isolated from the oil of fennel Foeniculum vulgare, Umbelliferae). 

Naturally occurring camphanes include the bomeols with an endo hydroxy group, the isobomeols with an exo OH and 2-camphanone (2-bonanone) referred to as camphor. (+)-Bomeol from the camphor tree Cinnamomum camphora (Lauraceae) and from the roots of ginger-like Curcuma aromatica (Zingiberaceae), both of which grow in Eastern Asia, is known as Borneo camphor. (-)-Isobomeol was isolated from Achillea filipendulina (Asteraceae).
