The study upon sage (Salvia officinalis L.) has been carried out at the Experimental Section of Department of Vegetables and Medicinal Plants, University of Life Sciences in Lublin. The aim of present study was to evaluate the yield and chemical composition of essential oil extracted from sage leaves harvested from a three-year plantation. The sage herb harvest date in the third year of cultivation had a significant impact on the yield of plants. Higher yield of fresh and dry herb, dry leaves, and essential oil was achieved in August (the second harvest time) than in May (the first harvest time). Chromatographic examination indicated the presence of 50 chemical compounds in sage essential oil. It was a variable percentage of essential oil components depending on the raw material harvest time. The main components of the sage essential oil were: 1,8-cineole (16.08-18.04%), α-thujone (10.40-21.51%) and camphor (5.24-18.08%).

Chemical composition, antimicrobial and cytotoxic activities of commercial essential oils’ samples from the aerial plant parts of H. officinalis, R. officinalis and S. officinalis were investigated. Analyses by GC-FID and GC-MS confirmed 52 oil components. The major constituent of the H. officinalis oil was cis-pinocamphone (34.4%), followed by transpinocamphone (23.3%), and β-pinene (11.3%). Analysis of R. officinalis oil revealed 1.8-cineol as a major constituent (43.8%), as well as transpinocamphone (12.5%), α-pinene (11.5%) and β-pinene (8.2%). The most dominant constituent of S. officinalis oil was cis-thujone (32.7%), in addition to camphor (17.2%), 1.8-cineol (10.1%), α-pinene (8.6%), transthujone (7.7%) and camphene (7.3%). The essential oil antimicrobial activity assay was performed by the use of microdilution method against oral Candida spp. and bacteria, the major causative agents of a number of human oral disorders; all of them were susceptible to tested concentrations of H. officinalis, R. officinalis and S. officinalis essential oils, although the oil of S. officinalis exhibited the lowest antimicrobial potential. The results obtained in this study encourage use of investigated essential oils from Lamiaceae family in development of safe natural agents for prevention and/ or alternative therapy of human oral diseases. However, a special care during development of an effective natural preparation is required.
