Until microbial actions essential oil are one of the most extensively studied aspects of botanical medicine, varius aromatic plant species are being investigated for their pharmacological properties. Salvia leriifolia Benth (Lamiaceae), as a native plant species of South Khorasan province, has significant applications in medicine, pharmacology and food industries. In current study, S. leriifolia essential oil was tested for its antibacterial activity against cariogenic bacteria and then relation between antimicrobial property and plant fenology was investigated. Method: Essential oil of plant leaves at three different phonologic stages (vegetative, flowering and seed formation) was extracted by steam distillation method and then its antibacterial activity against Streptococcus mutans (ATCC:1683), Streptococcus sangius (ATCC:1449) and Actinomyces viscosus (ATCC:1202) was evaluated by Agar dilution method. The study was conducted based on Completely Randomized Design (CRD) and data were analyzed with JMP and MSTATC softwares. Result: Minimum inhibitory concentrations (MICs) of essential oil at vegetative stage were 21, 25 and 12.5mg/ml against Streptococcus mutans, Streptococcus sangius and Actinomyces viscosus, respectively. The evaluated MICs at flowering stages were 21, 21 and 25 mg/ml for above mentioned bacteria with the same order. At the stage of seed formation, MIC was 25 mg/ml for all bacteria. Conclusion:. Results showed that the essential oil of S. leriifolia had significant inhibitory effect on growth of all tested bacteria. In folowering time, the plant showed more antibacterial activity than other phenologic stages and Actinomyces viscosus showed the most sensitive bacteria .
