Comparative study of the leaf oil of Juniperus macropoda growing in garhwal regions of Uttranchal (India)

Leaf oils of Juniperus macropoda collected from different localities (Hindolkhal and Mussorie) of Garhwal Himalaya (Uttaranchal) exhibited much variation in their yield and composition. Oil yields in the Hindolkhal and Mussorie samples were 1.2% and 0.52% respectively. In the Hindolkhal sample, β-elemene (42.5%) was the main constituent of oil, followed by t-sabinene hydrate (8.8%) and α-cubebene (7.9%), while in the Mussorie sample the main oil constituent was α-thujone (22.6%), followed by biformene (7.7%) and sabinene (5.8%).
