Ascomata of two truffle species, Tuber borchii and T. asa-foetida, both naturally growing in woodlands of the Basilicata region (southern Italy), were identified on the basis of ascospore morphology and compared under a volatile organic compound profile to determine the particular volatile organic compounds that characterize each taxon. Solid-phase microextraction-gas chromatography-mass spectrometry analysis of the samples showed the presence of 1-methyl-1,3-butadiene as a primary component in both truffles. T. asa-foetida showed a compound, toluene, not present in T. borchii, which creates the penetrating "solvent" smell of the truffle.
在意大利南部巴西利卡塔地区的林地中自然生长的两种块菌——波氏块菌（Tuber borchii）和臭块菌（T. asa-foetida），根据子囊孢子形态进行了鉴定，并在挥发性有机化合物谱图下进行比较，以确定表征每个分类单元的特定挥发性有机化合物。对样品进行的固相微萃取-气相色谱-质谱分析表明，两种块菌中均以1-甲基-1,3-丁二烯为主要成分。臭块菌有一种波氏块菌中不存在的化合物——甲苯，正是它产生了块菌那种刺鼻的“溶剂”气味。
