目的 研究苍术挥发油的气相色谱-质谱(GC-MS)联用指纹图谱与苍术燥性效应的谱效关系,初步明确苍术主要燥性成分。方法 采用GC-MS法对不同批次苍术(S1~S9)挥发油进行分析,以大鼠日均饮水量、全血黏度、肾脏中水通道蛋白2(AQP2)量为苍术燥性效应药效指标,采用灰色关联度分析法和正交偏最小二乘法相结合分析其谱效关系。结果 苍术发挥燥性效应是多种成分共同作用的结果,对燥性作用药效贡献较大的3个峰分别为31、28、33号峰,经过谱库检索分析鉴定出3个峰对应的成分分别为β-桉叶醇、马兜铃烯、异愈创木醇。结论 初步明确苍术主要燥性成分有β-桉叶醇、马兜铃烯、异愈创木醇,为苍术燥性物质基础研究提供参考。

[Abstract]
Objective To study the spectrum-effect relationship between GC-MS fingerprint of the volatile oil of Atractylodis Rhizoma and the dryness effect of Atractylodis Rhizoma, and clarify the main dryness components of Atractylodis Rhizoma.Methods The volatile oil of different batches of Atractylodis Rhizoma (S1-S9) were analyzed by GC-MS. Using the daily drinking amount of water, the viscosity of whole blood, and the content of aquaporin 2 (AQP2) in the kidney of rats as the indexes of dryness effect of Atractylodes Rhizome, the spectrum-effect relationship was analyzed by the combination of grey relational grade and orthogonal partial least square method.Results The dryness effect of Atractylodis Rhizoma was the combined action of multiple components, and the peaks of the major contribution to dryness effect were 31, 28, and 33, respectively. The corresponding components of the three peaks were β-eudesmol, (-)-aristolene, and bulnesol, which were identified by the spectral library retrieval analysis.Conclusion The main dryness effect components of Atractylodis Rhizoma are β-eudesmol, (-)-aristolene, and bulnesol, which provide a reference for investigating the material basis of dryness effect of Atractylodis Rhizoma.
