The essential oils are found in a great number of Lamiaceae family species, but few researches were carried out on this subject. This work had as a goal to identify the Leonurus sibiricus L. (rubim) essential oil composition. Rubim leaves and flowers in infusion are able to avoid vomit, diarrhea, and are also indicated in cold, cough, bronchitis and rheumatisms cases. In order to know what are the phytochemical compositions involved, it was used the gas chromatography techniques with mass spectrometry (GC-MS) as methodology. The results showed 70% volatility compound by trans-cariophylene, alpha-humulene and germacrene-D. Other substances like gamacadinene, beta-bourborene and alpha-copaene were found like compounds of this essential oil species.
