abstract a comparison of yields and chemical composition of the essential oils obtained by water distillation from the flowers, leaves and stems of salvia aethiopis l. and salvia glutinosa l., originating from the southeast region of serbia was carried out. the oil yields of s. aethiopis l. and s. glutinosa l. were 0.5% and 0.2% for the leaf; and 0.4% and 0.2% for the flower, respectively. the chemical composition of the oils was also different, although they belong to the same genus. the main components in the oil of s. aethiopis were: bicyclogermacrene (29.0% in flower), -copaene (22.4% in leaf), spathulenol (20.1% in stem) and germacrene d (13.5% in stem). the oil of s. glutinosa has the following principal components: caryophyllene oxide (28.9% in leaf), humulene epoxide ii (13.8% in leaf), -caryophyllene (9.0% in flower) and -humulene (5.9% in flower).
