Comparative Analysis of Volatile Compounds in the Flower Buds of Three Panax Species Using Fast Gas Chromatography Electronic Nose, Headspace-Gas Chromatography-Ion Mobility Spectrometry, and Headspace Solid Phase Microextraction-Gas Chromatography-Mass Spectrometry Coupled with Multivariate Statistical Analysis

Molecules
The flower buds of three Panax species (PGF: P. ginseng; PQF: P. quinquefolius; PNF: P. notoginseng) widely consumed as health tea are easily confused in market circulation. We aimed to develop a green, fast, and easy analysis strategy to distinguish PGF,

HS-SPME-GC-MS determination of volatile components in toasted oak chips

, 2018
Volatile compounds are present in a high content in oak and that have a great impact on wood-matured wine aroma. The main volatiles in oak are volatile phenols, such as guaiacol, eugenol and syringol, phenolic aldehydes such as vanillin and syringaldehyde, furanic aldehydes, such as furfural and oak lactones.
