| 判断渝东北地产平术化学分型，为平术的临床合理使用及其品质评价提供科学依据。方法 采用GC-MS技术测定不同产地平术和苍术药材10批样品，分析其质谱图，用SIMCA14.1软件和SPSS19.0软件进行模式识别分析，并通过MSSS质谱图库检索及标准品对照对显著差异的特征化合物进行鉴定。结果 渝东北地产平术化学分型属茅苍术型，与平术植物形态分类属苍术的结果吻合，并鉴定出了影响苍术化学生态分型的17个关键化合物。结论 平术化学生态分型属茅苍术型，且品质与茅苍术接近。 |

| OBJECTIVE To judge the chemoecotype of Ping Zhu from the northeast of Chongqing and provide a scientific basis for the clinical use and the quality evaluation of Ping Zhu. METHODS GC-MS was used to determine samples of Ping Zhu and Atractylodis rhizoma from different sources. Data were processed with SIMCA 14.1 software and SPSS19.0 software for pattern recognition analysis. The MSSS spectrum base and standard were used to identify the main compounds. RESULTS The Ping Zhu from the northeast of Chongqing was confirmed as Atractylodes lancea (Thunb.) DC. It was consistent with the results of the plant morphological classification. 17 key compounds affecting the chemoecotype of Atractylodis rhizoma were identified. CONCLUSION The chemoecotype of Ping Zhu belongs to the type of Atractylodes lancea (Thunb.) DC， and they have similar qualities. |
