CICCIO, José F.; SOTO, Victor H. e POVEDA, Luis J.. Essential oil of Lepechinia schiedeana (Lamiaceae) from Costa Rica. Rev. biol. trop [online]. 1999, vol.47, n.3, pp.373-375. ISSN 0034-7744.
The composition of the essential oil isolated by steam distillation from aerial parts of the Costa Rican herb Lepechinia schiedeana (Schlecht) Vatke (Lamiaceae) collected in El Empalme, Costa Rica, was determined by capillary gas chromatography (GC) and coupled gas chromatography-mass spectrometry (GC-MS) analyses. Fifty-one components were identified corresponding ca. 93% of the oil. The major components were -pinene (26.6%), cis -pinocamphone (25.1%), -3-carene (6.1%), trans -pinocamphone (4.0%), camphor (3.8%) and -caryophyllene (3.7%).
