Abstract
The leaf essential oil composition of Annona squamosa L., collected from the lower region of Himalaya was investigated using gas chromatography-flame ionisation detector (GC-FID) and GC-mass spectrometry (GC-MS). A total of forty-three constituents, representing 88.6% of the total oil composition were identified. The essential oil was primarily composed of sesquiterpenoids (sesquiterpene hydrocarbons: 63.4% and oxygenated sesquiterpenes: 21.8%). Major constituents of the oil were (E)-caryophyllene (15.9%), γ-cadinene (11.2%), epi-α-cadinol (9.4%), (Z)- caryophyllene (7.3%), γ-muurolene (5.4%), α-humulene (5.2%), viridiflorene (5.0%), α-cadinol (3.9%), aromadendrene (2.9%), δ-cadinene (2.9%), α-cadinene (2.9%), (2Z,6Z)-farnesal (2.2%) and caryophyllene oxide (2.1%).
