Composition of Tunisian Pistachio Hull Essential Oil during Fruit Formation and Ripening (original) (raw)

2008, Journal of Essential Oil Research

The Anacardiaceae family is known for its species producing essential oil, such as Pistacia genus. As for pistachio tree (Pistacia vera), its fruit is composed by a fleshy and odorant envelope or hull (mesocarp + epicarp) covering the hard shell (endocarp) containing an edible seed. We aimed to characterize the oils of pistachio hulls (Pistacia vera L.) during fruit development. Fruits were sampled in the region of Kairouan (Middle of Tunisia). Yields generally increased and ranged between 0.1-0.4% on a dry weight basis. Monoterpene hydrocarbons, mainly represented by alpha-pinene (15.0-47.4%) and terpinolene (32.2-51.1%) were prominent during all fruit development, reaching 90.3% of the oil at full ripeness.
