Comparison of Volatile Compounds of Fresh <i>Boletus edulis</i> and <i>B. pinophilus</i> in Marmara Region of Turkey

Abstract

Boletus edulis and B. pinophilus are commonly consumed edible species of Boletus spp. in Turkey, 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 B. edulis and B. pinophilus. 1-octen-3-ol (79.75), 2-octen-1-ol (13.18), 1-octen-3-one (2.52), (E)-2-octenal (1.21) in B. edulis 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 B. pinophilus were identified as main volatile aroma compounds (%), respectively. The present study is the first report on the volatile constituents of B. edulis and B. pinophilus collected from Turkey.
