Analysis by GC and GC-MS of the essential oil obtained from aerial parts of
Erechtites hieracifolia revealed 22 components (93% of the total compositi
on). The major constituents were found to be alpha -pinene, myrcene, (E)-be
ta -ocimene, (E)-caryophyllene and germacrene D; the enantiomeric distribut
ion of alpha -pinene, sabinene, beta -pinene, limonene and linalool was stu
died by multidimensional HRGC-HRGC. The major component was alpha -pinene (
48%) with an enantiomeric purity of 100% for (IR)-(+)-alpha -pinene. Copyri
