Floral scent compounds emitted from Petunia mitchell were analyzed using high-resolution atmospheric pressure corona discharge ionization mass spectrometry (APCDI-MS) in negative-ion mode. Negative ions originating from the scent compounds were observed at m/z 151 and 184, identified as deprotonated vanillin (VL; 152 Da) [VL - H]- and O2- adduct [VL + O2]-, respectively. The appearance of vanillin as the dominant scent compound is most likely resulted from the transformation of isoeugenol, known as the major endogenous volatiles in P. mitchell, in the atmosphere.
