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.
