Chemical Compounds and Biological Activity of Turkish Santolina chamaecyparissus L. Essential Oil by Microwave Assisted Distillation

Abstract

Aim of study:The essential oil of S. chamaecyparissus (SEO) was isolated by microwave assisted distillation system to analyze the antioxidant and antimicrobial activities.Area of study: S. chamaecyparissus were collected from Osmaniye province of Turkey in April 2018. Material and method: The chemical constituents and groups (by GC/MS and FTIR spectroscopy, respectively), antioxidant (by DPPH technique) and antimicrobial activities (by agar disc diffusion method) of SEO were investigated.Main results: Twenty aromatic compounds were determined and artemisia ketone (39.83%), camphor (17.65%), β-phellandrene (8.03%) and β-bisabolene (7.32%) were the most abundant. IC50 values which were the indicators of antioxidant behavior of SEO, butylated hydroxytoluene (BHT) and gallic acid recorded as 88.301, 0.212 and 0.021 g/L respectively. The antimicrobial activity results showed that all tested microorganisms (Escherichia coli, Streptococcus mutans, Bacillus cereus, Bacillus subtilis, Candida albicans) were highly inhibited.Highlights: SEO could be a good source of monoterpenes especially artemisia ketone. Its herbaceous fragrance may provide a new usage area in men's perfumery.
