The predominant constituent was β-caryophyllene (27.4%) (Table 1). Minor sesquiterpene hydrocarbons in 3.01–6.59% yield like cycloisosativene, α-copaene, trans-α-bergamotene, β-farnesene, germacrene D, bicyclogermacrene, α-humulene, and δ-cadinene occurred in C. punctatum oil. Among the oxygenated sesquiterpenes, spathulenol (1.26%), viridiflorol (2.12%), and caryophyllene oxide (2.42%) formed the notable constituents.
