Volatile Constituents of Aerial Parts of Euphorbia aellenii Rech.f. and E. microsciadea Boiss. from Iran

The volatile constituents of aerial parts of Euphorbia aellenii Rech.f. and E. microsciadea Boiss. were analyzed by gas chromatography (GC) and GC-mass spectrometry (MS) methods. The main volatile constituents of E. aellenii were phytol isomer (47.3%), camphene (31.9%) and caryophyllene oxide (20.6%), while the major volatile components of E. microsciadea were trans-anethole (74.5%), limonene (7.7%), hexadecanoic acid (6.8%), fenchone (6.0%) and phytol isomer (4.9%).
