A flow-injection mass spectrometric (FIMS) fingerprinting method in combination with principal component analysis (PCA) was used to study the geo-herbalism of Evodiae Fructus (EF) samples. Twenty four EF samples from different regions in China were collected and analyzed. The PCA scores plot showed that the samples from Guizhou Province were scattered in different groups, however, most of the samples from other provinces were basically scattered in the same group. Nine characteristic compounds responsible for the classification of the samples were tentatively characterized. These nine compounds might help differentiating EF samples from different regions.
采用流动注射质谱（FIMS）指纹图谱法结合主成分分析（PCA）研究吴茱萸（EF）样品的道地性。收集并分析了来自中国不同地区的24个EF样品。PCA得分图显示，贵州省的样品分散在不同组中，而其他省份的大多数样品基本分散在同一组中。初步鉴定了9种负责样品分类的特征化合物。这9种化合物可能有助于区分不同地区的EF样品。
