This work presents the analysis by GC-MS of volatile metabolites of six Lamiaceae from Arauca (Colombia). In stems and leaves of Eriope crassipes were determined as the most abundants: citronellic acid (53,8% and 66,2%), and methyl citronellate (15,7% and 14,5%). In the inflorescences of Hyptis conferta were identified: -cadinol (49,4%), and caryophyllene oxide (13,0%). From leaves and flowers of Hyptis dilatata were found: δ-3-carene (11,0% and 0,5%), camphor (43,8% and 12,2%), bornyl acetate (3,2% and 25,5%), E-caryophyllene (12,8% and 22,3%), and palustrol (6,0% and 10,3%). In the leaves of Hyptis brachiata were recognized: E-caryophyllene (8,3%), α- humulene (19,8%), and germacrene D (13,0%). The principal compounds in leaves and flowers of Hyptis suaveolens were: α-phellandrene (9,4% and 0,4%), limonene (10,5% and 2,5%), 1,8-cineole (1,3% and 15,2%), fenchone (10,8% and tr), E-caryophyllene (26,3% and 8,0%), and germacrene D (6,7% and 14,0%). In the leaves of Hyptis mutabilis were determined: sabinene (6,6%) β-elemene (6,8%), germacrene D (14,9%), β-selinene (8,8%), α-selinene (9,1%), and bicyclogermacrene (6,1%), as the most abundants.
