Essential oil composition of aerial parts from Algerian Anacyclus monanthos subsp. cyrtolepidioides (Pomel) Humphries

The chemical composition of the essential oil from the aerial parts of Anacyclus monanthos subsp. cyrtolepidioides (Pomel) Humphries (Asteraceae) growing in a semi-arid region of Algeria was investigated for the first time. The essential oil was obtained by hydrodistillation and fully characterized by gas chromatography-mass spectrometry (GC-MS). A total of 97 compounds were identified. The essential oil was found to be rich in trans-chrysanthenyl acetate (9.8 ± 2.0%), (E)-β-farnesene (7.4 ± 1.5%), germacrene D (6.9 ± 1.3%) and myristicin (4.8 ± 0.8%).
