摘要：
The main goal of the present study is to evaluate the effects of cellulase pre-treatment on the yields, chemical composition, antioxidant and antimicrobial activities of the essential oils of Salvia officinalis L. The results showed that application of cellulase induced 25.61% increase in the essential oil yields. GC/MS analysis revealed the presence of 29 compounds in Salvia officinalis L. essential oil. Higher amounts of oxygenated monoterpenes were existed in the essential oil of enzymatic pre-treatment (64.42%) in comparison with control (53.28%). Meanwhile, the antioxidant and antimicrobial activities were also assessed in vitro, cellulase pre-treatment extracted essential oil exhibited significantly stronger antioxidant ability of reducing power and radical scavenging activity of DPPH, and showed relatively good antimicrobial activity with the Diameter of inhibition zones, the minimum inhibitory concentration (MIC) and the minimal bactericidal concentration (MBC) values against two gram-positive bacteria. Cellulase pre-treatment could be useful for enhancing yield and biological activities of the essential oils, and hold a good potential for use in food and pharmaceutical industries. © 2017, Editorial Office of Journal of CIFST.
