<i>In vitro</i> biological activities and fatty acid profiles of <i>Pistacia terebinthus</i> fruits and <i>Pistacia khinjuk</i> seeds

<div><p>This study reports <i>in vitro</i> anticholinesterase, antioxidant and antimicrobial effects of the <i>n</i>-hexane, dichloromethane, ethanol and ethanol–water extracts prepared from <i>Pistacia terebinthus</i> L. fruits and <i>Pistacia khinjuk</i> Stocks seeds as well as their total phenolic and flavonoid contents, and fatty acid compositions. Ethanol and ethanol–water extracts of both species exhibited higher anticholinesterase activity than galanthamine. Among ABTS, DPPH and CUPRAC assays, the highest antioxidant capacity of the extracts was found in the last one. <i>P. terebinthus</i> ethanol extract being rich in flavonoid content showed the best cupric reducing effect. All extracts possessed no antimicrobial activity. The main fatty acid in <i>P. terebinthus</i> fruits (52.52%) and <i>P. khinjuk</i> seeds (59.44%) was found to be oleic acid. Our results indicate that <i>P. terebinthus</i> fruits and <i>P. khinjuk</i> seeds could be a good source of anticholinesterase compounds, and could be phytochemically investigated.</p></div
