The volatile compounds of Panax ginseng C.A. Meyer analyzed to interpret whether cultivation methods affect volatile compounds. The volatile compounds in Panax ginseng C.A. Meyer cultured with 3 different cultivation methods such as good agricultural practice, organic cultivation method, and general cultivation method were isolated by solid-phase microextraction fiber (polydimethylsiloxane 65 μm) and identified by gas chromatography mass spectrometry. Then, the scattering patterns of volatile compounds compared by principal component analysis. As the results, the 14 volatile compounds were identified from 30 ginseng samples and consisted mainly of sesquiterpene hydrocarbons. The differences among the different cultivation methods of the samples were obvious from the PC1 and PC2 scatter point plot. As the conclusion, the cultivation methods can affect to produce the volatile component of ginseng root. The organic and good agriculture practice cultivation can increase the ginseng characteristic volatile compounds.
采用固相微萃取纤维（聚二甲基硅氧烷 65μm）提取并结合气相色谱-质谱联用技术分析鉴定了不同栽培方法（包括良好农业规范、有机栽培法和常规栽培法）栽培的人参中的挥发性成分，以探讨栽培方法是否会影响人参中的挥发性成分。从 30 个人参样品中鉴定出了 14 种挥发性成分，主要由倍半萜类化合物组成。通过主成分分析比较了不同栽培方法样品的挥发性化合物分布图谱，结果表明，不同栽培方法的样品之间差异明显，PC1 和 PC2 散点图上的分布也不同。由此得出结论，栽培方法会影响人参根中挥发性成分的产生，有机和良好农业规范栽培可以增加人参的特征性挥发性化合物。
