Chemical Composition of the Essential Oil From<i>Eupatorium adenophorum</i>Spreng

Abstract

Abstract The GC and GC/MS analysis of the essential oils from the aerial parts of Eupatorium adenophorum collected from different localities of Kumaun and Garhwal revealed the dominant presence of amorph-4-en-7-ol (5.8–17.7%), bornyl acetate (7.6–15.9%), p-cymene (0.1–16.6%), 3-acetoxyamorpha-4,7(11)-dien-8-one (0.3–16.3%), α-phellandrene (1.5–9.6%), camphene (≶0.1–8.9%), α-bisabolol (1.7–7.8%), α-cadinol (0.6–6.2%) and amorph-4,7(11)-dien-8-one (3.2–5.7%). Amorphene derivatives (19.8–41.4%) may be considered as characteristic constituents of E. adenophorum.
