Composición química del aceite esencial de flores De Salvia leucantha Cav. (Lamiaceae)

The essential oil (AE) in Salvia Leucantha Cav. flowers was extracted by steam distillation with a yield of 0.16%. To determine the composition of the S. leucantha Cav. essential oil, the authors used a gas chromatograph coupled to a Shimadzu QP-2010 plus mass spectrometer. Next, the results were compared against the NITS-08 database and the retention rates (IR) reported in the literature. In addition, the results established the presence of monoterpenes (M) such as, bornyl acetate (9.8%), α-pinene (4.4%), d-camphene (3.3%), and β-pinene (2.4%), and of sesquiterpenes (S), such as karyophylene (10.0%), β-farnesene (10.7%), germacrene D (10.6%), and aristolene (17.2%), wherein aristolene stands out as a major component of the essential oil extracted from S. leucantha flowers. Lastly, two aliphatic chain hydrocarbons known as “octadecane” and “icosane” were further identified.
