The genus Pistacia includes different species diffused worldwide able to produce oleoresins used in several folk medicines. Oleoresins are phytocomplexes exudate from the trunk of plants and possess several biological properties thanks to the simultaneous presence of essential oils, di- and triterpenes and phenols. Pistacia vera L. oleoresin chemical composition is not well known due a lack of studies respect to other Pistacia species. The aim of this work is to report the terpenes profile of this phytocomplex collected in Sicily (Italy) by means of a GC-FID and GC-MS analysis of its essential oil and less volatile fractions. Results show that this profile is peculiar and different from the other Pistacia species mainly in terms of relative percentages of its components. ?-pinene is the main compound of the essential oil, while dammarane and tirucallene derivatives are the main triterpenes identified in the less volatile fractions. This work represent, up to now, the first complete terpenoidic chemical profile of the oleoresin of Pistacia vera L. and should be considered as first step for a deeper evaluation of biological properties and future application of this phytocomplex.

Abstract

The genus Pistacia includes different species diffused worldwide able to produce oleoresins used in several folk medicines. Oleoresins are phytocomplexes exudate from the trunk of plants and possess several biological properties thanks to the simultaneous presence of essential oils, di- and triterpenes and phenols. Pistacia vera L. oleoresin chemical composition is not well known due a lack of studies respect to other Pistacia species. The aim of this work is to report the terpenes profile of this phytocomplex collected in Sicily (Italy) by means of a GC-FID and GC-MS analysis of its essential oil and less volatile fractions. Results show that this profile is peculiar and different from the other Pistacia species mainly in terms of relative percentages of its components. ?-pinene is the main compound of the essential oil, while dammarane and tirucallene derivatives are the main triterpenes identified in the less volatile fractions. This work represent, up to now, the first complete terpenoidic chemical profile of the oleoresin of Pistacia vera L. and should be considered as first step for a deeper evaluation of biological properties and future application of this phytocomplex.
