Abstract
The oil of Feijoa skin (Feijoa sellowiana, family Myrtaceae) was isolated by hydrodistillation in a Clevenger-type apparatus and analyzed by GC-MS analysis. As a result, 76 components were isolated. Among 19 peaks identified which three were reported for the first time in this plant (Elixene, Linalylanthranilate and Farnesol). The sesquiterpene group was predominant, accounting for 97.8% of the total oil. Of which Caryophyllene was the most abundant 17.7%, followed by Germacrene D14.4%, Humulene 10.5%, Ledene 14%, Spathulenol 8.5%, Cadina-3,9-diene 8.3%, Farnesol 8%, Linalylanthranite 5.6%, β-elemene 4.8%, α-Cubebene 2.7%. Other constituents were also present in oil such as Octanone 5.3%, D limoneme 0.17%, Ocimene 1.6%, Benzoicacidmethylester 1.1%.
