Terpenes and Sesquiterpenes in Cold‐pressed Orange Oil

SUMMARY As part of a study of the flavor constituents of orange oil, 13 terpenes and 11 sesquiterpene hydrocarbons were isolated and identified. The terpene hydrocarbons were identified as α‐thujene, α‐pinene, camphene, 2,4‐p‐mentbadiene, sabinene, myrcene, Δ‐3‐carene, α‐phellandrene, α‐terpinene, limonene, Δ‐3‐terpinene, p‐cymene, and terpinolene. The sesquiterpene hydrocarbons were identified as α‐copaene, α‐ylangene, β‐copaene, β‐elemene, caryophyllene, β‐ylangene, farnesene, α‐ and β‐humulene, valencene, and Δ‐cadinene.
