«HS-70, head-space extraction at 70°C; HS-80, head-space extraction at 80°C; Deryng, vapour distillation in a Deryng apparatus; ASE, accelerated so!vent extraction hThe amount of a volatile compound extracted by a given method of extraction is expressed on the percentage scalę (as semi-quantitatively estimated from its respective peak height relative to the sum for all the volatile compounds)
cEmboldening indicates the chemotaxonomic advice compound (thujone) estab-lished in previous work [14]
