The Composition of the Volatile Fraction and the Enantiomeric Distribution of Five Volatile Components of Faustrime Oil (Monocitrus australatica x Fortunella sp. x Citrus urantifolia)

Abstract

The composition of the volatile fraction of faustrime essential oil has been determined by GC and GC/MS on RTX-5 and RTX-Wax columns. The enantiomeric distribution of five volatile components has been determined by direct chiral GC using a DETTBUSILßCDX column.

The oil was found to contain over 57% hydrocarbons and 41–42% oxygenated compounds. The former class was characterized by limonene, β-phellandrene and γ-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 (β-pinene, sabinene, limonene, linalool and α-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.
