Abstract

Pistacia lentiscus L., a plant that belongs to the family of Anacardiaceae, is a small evergreen tree native to the Mediterranean region. The trunk of the plant produces a resin with therapeutic value - and not only - recognized since ancient times. It is an antioxidant and antimicrobial substance. Today, apart from its therapeutic use, it is known as a flavoring and as a raw material of high quality lacquer. The parts of the plant that are exploited by the industry are its resin, leaves, and fruits. The chemical composition of the resin is made of polymer β-polymyrcene, the triterpene fraction, and the essential oil. In most species, the P. lentiscus triterpene fraction comprises a neutral and an acidic fraction. However, the triterpene fraction of P. lentiscus from southern Crete contained only the neutral fraction, which-as assessed by GC/MS- contained neutral ingredients commonly found in the P. lentiscus resins, as well as methyl esters of triterpenic acids that are detected in their acid-free form in resins of other varieties (e.g. P. lentiscus var. Chia) in other regions. In the analysis of the triterpene fraction, 16 compounds were detected of which 10 were identified: six neutral compounds and four methyl esters. The essential oils of the resin and leaves samples were collected by the use of a microdistillator and an improvised professional distillation system, respectively. Analysis by GC-MS showed 21 essential oil components in the resin sample and 58 in the leaves sample. 17 Components were identified from the former sample and 51 components from the latter, respectively. The resin-produced essential oil comprises 94.56% α-pinene, a value that never exceeded 79% in any literature report.
