The essential oils of the leaves of Hyptis suaveolens (L.) Poit collected from two different sources were isolated by hydrodistillation. The oils were analysed by GC and GC_MS; 36 constituents were identified in the oil of sample collected from the campus of Lagos State University (LASU), while 33 constituents were identified in the oil of sample from Obafemi Awolowo University (OAU). α ‐Pinene (13.6%), sabinene (13.2%), p ‐cymene (11.7%), terpinen‐4‐ol (9.8%) and terpinolene (6.3%) were the major monoterpenes in the LASU oil sample, while sabinene (30.0%), terpinen‐4‐ol (11.4%), terpinolene (5.6%), 1,8‐cineole (5.2%), β ‐pinene (4.4%) and α ‐terpinene (4.2%) were the main monoterpenes in the OAU oil sample. β ‐caryophyllene (5.1_5.9%) and trans ‐ α ‐bergamotene (1.6_5.2%) represented the major sesquiterpenes in both oils.
