Abstract The essential oil of Pulicaria glutinosa Jaub. was examined by GC and GC/MS. The oil was characterized by its high proportion of sesquiterpenes. Of the 37 components detected, the most abundant were Î²-elemene (11.8â16.4%), Ï-cadinol (12.4â14.2%) and Î±-cadinol (8.4â10.5%). Minor differences were detected between the oils isolated from samples collected in different years.
