Abstract

ABSTRACT
Essential oil of Santolina pectinata lag. aerial parts was obtained by hydrodistillation and analyzed, for the first time, by using gas chromatography and gas chromatography-mass spectrometry (GC-MS (EI)). 33 components were identified which a non terpenic oxygenated compound i.e., (Z)-heptadeca-10,16-dien-7-one strongly dominated the oil composition with 28%. The structure of this natural compound was determined for the first time by a Positive electro spray ionization time-of-flight mass spectrometry (ESI (+) -TOF-MS, one-dimensional and two-dimensional nuclear magnetic resonance spectroscopy.
