| studies on volatile organic compounds of tuber borchii and t. asa-foetida. | 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 ... | 2012 | 22685100 |
