Abstract Fifteen compounds were identified in the essential oil of Hyptis crenata Pohl, which was analyzed by GC/MS. The main oil components were α-pinene (15.5%), β-pinene (10.5%), camphor (17.3%), and β-caryophyllene (10.7%). The volatile concetrate isolated from the distillation water contained 1,8-cineole (11.9%), camphor (37.3%) and β-caryophyllene (14.7%).
