<p class=MsoNormal><i style='mso-bidi-font-style:normal'><span lang=EN-US>Boletus edulis</span></i><span lang=EN-US> and <i style='mso-bidi-font-style:normal'>B. pinophilus</i> are commonly consumed edible species of <i style='mso-bidi-font-style: normal'>Boletus</i> spp. in <st1:country-region w:st="on"><st1:place w:st="on">Turkey</st1:place></st1:country-region>, which are also exported to some European countries. In this study, twenty-three volatile compounds were determined with Headspace Solid-Phase Microextraction / Gas Chromatography / Mass Spectrometry (HS-SPME/GC/MS) in both <i style='mso-bidi-font-style:normal'>B. edulis</i> and <i style='mso-bidi-font-style: normal'>B. pinophilus</i>. 1-octen-3-ol (79.75), 2-octen-1-ol (13.18), 1-octen-3-one (2.52), (E)-2-octenal (1.21) in <i style='mso-bidi-font-style: normal'>B. edulis</i> and 1-octen-3-ol (55.97), 2-octen-1-ol (13.55), 3-octanone (7.43), (E)-2-octenal (6.79), 1-octen-3-one (5.80) and 1,7,7-trimethyl-heptan-2-one (2.04), 2-propenoic acid (1.95) and 1,3-octadiene (1.75) in <i style='mso-bidi-font-style:normal'>B. pinophilus</i> were identified as main volatile aroma compounds (%), respectively. The present study is the first report on the volatile constituents of <i style='mso-bidi-font-style: normal'>B. edulis</i> and <i style='mso-bidi-font-style:normal'>B. pinophilus</i> collected from <st1:country-region w:st="on"><st1:place w:st="on">Turkey</st1:place></st1:country-region>.<b style='mso-bidi-font-weight:normal'><o:p></o:p></b></span></p>
