Composition of the essential oil of <i>Erechtites hieracifolia</i> from Bolivia

Abstract

Abstract Analysis by GC and GC–MS of the essential oil obtained from aerial parts of Erechtites hieracifolia revealed 22 components (93% of the total composition). The major constituents were found to be α‐pinene, myrcene, (E) ‐β‐ocimene, (E) ‐caryophyllene and germacrene D; the enantiomeric distribution of α‐pinene, sabinene, β‐pinene, limonene and linalool was studied by multidimensional HRGC–HRGC. The major component was α‐pinene (48%) with an enantiomeric purity of 100% for (1 R )‐(+)‐α‐pinene. Copyright © 2001 John Wiley &amp; Sons, Ltd.
