The volatile compositions in dried white ginseng according to species (Panax ginseng, Panax notoginseng, and Panax quinquefolius) were analyzed and compared by applying multivariate statistical techniques to gas chromatography-mass spectrometry data sets. Main volatile compounds of ginseng species in the present study were sesquiterpenes, such as bicyclogermacrene, (E)-β-farnesene, β-panasinsene, calarene, α-humulene, β-elemene, etc. In particular, α-selinene, α-terpinolene, β-bisabolene, β-phellandrene, β-sesquiphellandrene, zingiberene, germacrene D, limonene, α-gurjunene, (E)-caryophyllene, δ-cadinene, (E)-β-farnesene, α-humulene, bicyclogermacrene, longiborn-8-ene, β-neoclovene, and (+)-spathulenol were mainly associated with the difference between P. ginseng and P. notoginseng versus P. quinquefolius species. On the other hand, the discrimination between P. ginseng and P. notoginseng could be constructed by hexanal, 2-pyrrolidinone, (E)-2-heptenal, (E)-2-octenal, heptanal, isospathulenol, (E,E)-2,4-decadienal, 3-octen-2-one, benzaldehyde, 2-pentylfuran, and (E)-2-nonenal.
采用多元统计技术对气相色谱-质谱数据集进行分析和比较，研究了不同种（人参、三七和西洋参）干白参中的挥发性成分。本研究中人参属植物的主要挥发性化合物为倍半萜类，如双环倍半萜、（E）-β-法呢烯、β-帕那辛烯、卡拉烯、α-葎草烯、β-榄香烯等。特别是α-蛇床烯、α-松油烯、β-姜黄烯、β-水芹烯、β-大根香叶烯、姜烯、大根香叶二烯、柠檬烯、α-古芸烯、（E）-丁香烯、δ-杜松烯、（E）-β-法呢烯、α-葎草烯、双环倍半萜、长叶-8-烯、β-新丁香烯和（+）-spathulenol 主要与人参和三七与西洋参种之间的差异有关。另一方面，通过己醛、2-吡咯烷酮、（E）-2-庚烯醛、（E）-2-辛烯醛、庚醛、异spathulenol、（E，E）-2,4-癸二烯醛、3-辛烯-2-酮、苯甲醛、2-戊基呋喃和（E）-2-壬烯醛可以区分人参和三七。
