The composition of the volatile fraction and the enantiomeric distribution of five volatile components of faustrime oil (Monocitrus australatica x Fortunella sp x Citrus aurantifolia)

The composition of the volatile fraction of faustrime essential oil has been determined by GC and GCMS on RTX-5 and RTX-Wax columns. The enantiomeric distribution of five volatile components has been determined by direct chiral GC using a DETTBUSILbetaCDX column. The oil was found to contain over 57% hydrocarbons and 41-42% oxygenated compounds. The former class was characterized by limonene, beta-phellandrene and gamma-terpinene, representing together about 44-45% of the whole volatile fraction; among the oxygenated compounds, citronellal was the most abundant with levels up to 22-23%. The enantiomeric distribution of five components (beta-pinene, sabinene, limonene, linalool and alpha-terpineol) yielded combined results that were unlike any other citrus peel oil. The specific enantiomeric ratios did show similarities with components found in other citrus oils
