Abstract
Pistachio (Pistacia vera L.) fruit is well known for its oleaginous and edible seed. Less information is available about the hull constituted by the epicarp and the mesocarp. This part of the fruit contains an essential oil that can be valorized. Tunisia is one of the countries cultivating pistachio trees. This work presents essential oil composition of pistachio hulls (Mateur variety) from different geographical localities: Grombalia (North-East), Kairouan (Middle) and Sfax (Middle-East). Yields were more important in Sfax samples (0.53% on a dry weight basis). Alpha-terpinolene was the major compound for Grombalia fruits (35.7%), whereas Kairouan and Sfax samples where characterized by alpha-pinene (42.5 and 43.8% respectively). For all samples, monoterpene hydrocarbons predominated (more than 79.8% of the essential oil).
开心果(Pistacia vera L.)果实以其富含油脂和可食用的种子而闻名。关于由外果皮和中果皮构成的外壳的资料较少。这种水果的这一部分含有一种精油，可以使其增值。突尼斯是种植开心果树的国家之一。这项工作展示了来自不同地理位置的开心果壳(业余品种)的精油成分:Grombalia(东北部)，Kairouan(中部)和Sfax(中东)。产量在Sfax样品中更为重要(干重0.53%)。-松油烯是龙巴利亚(Grombalia)果实的主要成分(35.7%)，而凯鲁万(Kairouan)和斯法克斯(Sfax)果实的主要成分(分别为42.5%和43.8%)。对于所有样品，单萜烯烃占主导地位(超过79.8%的精油)。
