Espeletia weddellii Sch. Bip. ex Wedd, is a shrub with rosette growth form which grows in the Andes above 3500 m. The essential oil of the leaves of this plant, obtained by hydrodistillation, was analyzed by GC‐FID using two fused silica gel columns of different polarity and GC–MS on a 5% phenyl‐methypolisiloxane column. Forty‐five compounds, which make up 86.2% of the oil, were identified. The main constituents were p ‐cymene (20.0%), α ‐phellandrene (17.6%), α ‐pinene (14.3%), δ ‐3‐carene (6.0%), β ‐pinene (4.4%), and α ‐thujene (3.9%). Copyright © 2000 John Wiley & Sons, Ltd.
