Abstract Volatile compounds of kumquat (Fortunella margarita (Lour.) Swingle) leaf oil were isolated by hydrodistillation. The isolated volatiles were analyzed by GC-FID and GC/MS, which led to the identification of 106 compounds, representing 99% of the total composition. The leaf oil was characterized by being richer in sesquiterpenes than monoterpene compounds. Î³-Eudesmol (19.0%), elemol (18.8%) and Î²-eudesmol (12.4%) were the most abundant compounds of the leaf oil. In addition, germacrene D (8.9%), Î²-pinene (8.3%) and linalool (8.2%) were also found as secondary constituents.
