Abstract The essential oil obtained by hydrodistillation from leaves of Laggera pterodanta Sch. Bip. ex Oliv. was analyzed by GC and GC/MS. Twenty-three components were identified, of which 2,5-dimethoxy-p-cymene (30.5%), 10-epi-Î´-eudesmol (24.6%) and juniper camphor (7.5%) were the most significant.
