大気圧コロナ放電イオン化質量分析法を用いたペチュニア花弁の香気成分のアンビエント分析
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.
