A steam-distilled oil obtained from the aerial parts of Teucrium carolipuui Pau grown in Spain was analyzed by capillary GC and GUMS. Forty-four components were characterized, of which four were monoterpenes amounting to 1.4%, and 38 sesquiterpenes that totalled 97.9%. The oil contained P-caryophyllene (8.2%), 8-cadinene (14.3%), a-cadinol(7.2%) and 3-~-hydroxy-a-muurolene (9.4%) as major constituents. Other important components were found to be cadina-1,4-diene (4.3%), caryophyllene oxide (4.5%), l-epi-cubenol(4.1%) and cubenol(3.5%).
