title: Chemical Diversity of Essential Oils from Pinus Nigra Arn. Subspecies Growing in Tunisia
abstract: Abstract Background: The aim of this study was the determination of chemical diversity of Pinus nigra Arn essential oils. The work was conducted on needles collected from eighteen provenances of Black pine grown in common garden located in West-Northern Tunisia and belonging to four different subspecies ( P. nigra subsp. nigra , P. nigra subsp. salzmannii , P. nigra subsp. pallasiana and P. nigra subsp. laricio ). The GC analysis was carried out with a Gas Chromatograph coupled to a mass spectro
