Fifty-five compounds were identified in the flower oil (96.8% of total oil) and 58 in the leaf oil (89.4% of total oil). Both oils were characterised by the high amount of monoterpenes (59.1–75.6%), whereas sesquiterpenes were present in smaller quantity (21.2–29.2%). The main compounds in the flower oil were sabinene (18.5%), limonene (12.0%), β-phellandrene (12.0%) and terpinen-4-ol (10.6%), while in the leaf oil the most dominant were β-pinene (20.0%) and terpinen-4-ol (12.0%). The antimicrobial activity of the oils was determined using the agar diffusion and broth microdilution method against bacteria Staphylococcus aureus, St. epidermidis, Micrococcus luteus, Pseudomonas aeruginosa, Klebsiella pneumoniae, Escherichia coli and a yeast Candida albicans. The best inhibitory effect (MIC 0.6 mg/mL) was exhibited by the flower oil against St. epidermidis, K. pneumoniae and C. albicans, the leaf oil against M. luteus, and both oils against E. coli.

Composition and antimicrobial activity of salvia amplexicaulis lam. essential oil / Silvana Petrovic in The journal of essential oil research, Vol. 21 N° 6 (Novembre/Décembre 2009)

Fifty-one compounds (90.2% of the total oil) were identified. The oil was characterized by a high amount of sesquiterpenes (81.1%), with germacrene D (14.8%), viridiflorol (10.6%), caryophyllene oxide (10.5%), and β-caryophyllene (9.4%) being the main components. The microbial growth inhibitory properties of the oil was determined against Gram-positive bacteria Staphylococcus aureus, St. epidermidis, Micrococcus luteus, Gram-negative bacteria Pseudomonas aeruginosa, Klebsiella pneumoniae, Escherichia coli, and a yeast Candida albicans. The best inhibitory effect was detected against M. luteus, followed by the effects against St. epidermidis, St. aureus and C. albicans. Tested Gram-negative bacteria were more resistant than Gram-positive bacteria and C. albicans.
