To detect chemical components of the essential oil of Schisandra chinensis (Turcz.) Baill..
The essential oil was analyzed with GC/MS, heuristic evolving latent projections(HELP) resolution and overall volume integration method.
HELP method along with the data from GC/MS can be used to conduct the peak purity examination and resolution of overlapping peaks to obtain pure chromatogram and MS spectrum of each component. Fifty six components were separated and 49 of them were qualitatively and quantitatively analyzed. All the components represent about 98.27% of the total content.
The resolved pure chromatogram and MS spectrum can greatly enhance the reliability of similar searches in the commercial MS database and thus contribute to the accuracy of the qualitative and quantitative analysis of the essential oil.
检测五味子挥发油的化学成分。
采用气相色谱-质谱联用（GC/MS）、启发式演进特征投影（HELP）解析法和总体积积分法对挥发油进行分析。
HELP方法结合GC/MS数据可进行峰纯度检查和重叠峰解析，以获得各成分的纯色谱图和质谱图。分离出56个成分，对其中49个进行了定性和定量分析。所有成分占总含量的约98.27%。
解析得到的纯色谱图和质谱图可大大提高在商业质谱数据库中相似性检索的可靠性，从而有助于挥发油定性和定量分析的准确性。
