The volatile compounds of peaches (Prunus persica L.) obtained from five cultivars (Chongyanghong, Y1; Ruiguang 19, Y2; Zaohongxia, Y3; Zaohong 2, Y4; and Wuyuehuo, Y5) were analyzed by gas chromatography?olfactometry (GC?O), gas chromatography?mass spectrometry (GC?MS) and GC?flame photometric detection (FPD). A total of 40 odor-active volatile compounds were observed in the GC?O experiments. Amongst those compounds, hexanal, (Z)-3-hexen-1-ol, (E)-2-hexenal, 3-mercaptohexanol, nonanal, gamma-nonalactone, and gamma-decalactone contributed greatly to aroma of peach. In addition, thirty-four quantified compounds were demonstrated as important odorants according to odor activity values (OAVs > 1). Amongst these compounds, hexanal (OAV: 28?89), pentanal (OAV: 9?16), (E)-2-heptenal (OAV: 19?60), (E)-2-hexenal (OAV: 26?86), (E)-2-octenal (OAV: 10?42), (E)-2-nonenal (OAV: 8?94), gamma-decalactone (OAV: 13?34), delta-decalactone (OAV: 2?19), (R)-(?)-linalool (OAV: 29?76) and phenyl acetaldehyde (OAV: 4?59) were the most powerful compounds in five varieties of peach.

The aerosols generated from e-cigarettes are composed of liquid and gas phases resulting from vapourized e-liquid. The apportioning of substances from e-liquid into the liquid and gas phases during e-cigarette use has not been extensively studied. Partitioning of e-liquid components between the gas and the liquid phase of the aerosol influences the substances inhaled and exhaled by the users, leading to second-hand exposure. It seems important to determine which compounds and how much of them are transferred into the gas phase and may immediately enter the bloodstream. For this purpose, a method based on thermal desorption followed by gas chromatography coupled with tandem mass spectrometry (GC?MS/MS) in electron ionization mode was developed. As in a previous study, an automatic generator of an aerosol from an e-cigarette with a collection tube filled with melt-blown non-woven fabric discs and equipped with Tenax TA sorption tubes was used. The melt-blown non-woven fabric is designed to capture liquid phase compounds, while sorption tubes are meant to sorb compounds in the gas phase of the aerosol. To control the e-liquid mass changes before and after a puff session, quantitation based on the mass change tracking approach (MCT) was applied. Accuracy of the developed method ranged between 91% and 110% regardless of the spiking level, with precision and reproducibility better than 10%. The limits of detection (LODs) ranged from 0.015 to 0.076 ng of substance emitted/mg of consumed e-liquid, while limits of quantitation (LOQs) ranged from 0.045 to 0.23 ng of substance emitted/mg of consumed e-liquid. Most of the compounds are deposited in the liquid phase of the aerosol, while only trace levels of some substances may be observed in an actual, non-condensed gas phase.
