Abstract:

The research of chemical changes in ginseng processing has been focusing on saponins and sugars. In this paper, volatile components in ginseng were studied for the first time, which provide a substance basis for different processed ginseng. The volatile components and their derivative paths of fresh ginseng, sun-dry ginseng and red ginseng were studied by gas chromatography-mass spectrometry(GC-MS/MS). The volatile components were detected and analyzed using TG-5SILMS nonpolar GC column, with He as the carrier gas through the NIST MS Spectral Database. Thirty, thirty-three and thirty-four species of volatile compounds in fresh ginseng, sun-dry ginseng and red ginseng were detected, respectively. The content of (-)-spartak alcohol in sun-dry ginseng is 31.98 times higher than that in the fresh ginseng, while the levels of eight volatile components such as octanal in sun-dry ginseng is three times higher than those in the fresh ginseng. The contents of ten volatile components such as cyclodecanone in red ginseng are 3 times higher than those in the fresh ginseng. Four volatile compounds in sun-dry ginseng and in red ginseng are not detected in fresh ginseng.
