Abstract:
Objective: To study the content determination of atractylodin, atractylon, and β-eudesmol in Atractylodis Rhizoma by GC and characteristic spectrum in order to provide a scientific basis for the quality control. Methods: Using GC and Agilent HP-5 capillary column, taking nitrogen as carrier gas, FID as detector, temperature programming, split ratio, injection port temperature: 250℃, detector temperature: 250℃, column temperature: 130℃; The contents of atractylodin, atractylon and β-eudesmol of 25 samples between Chengde and purchased from other markets were determined by external standard method. The characteristic spectrum was set up and the similarity was analyzed by Estimating System of Similarity on the Chinese Medicine Fingerprint Chromatogram. Results: The determination method and characteristic spectrum by GC for atractylodin, atractylon, and β-eudesmol in Atractylodis Rhizoma were established. Nine characteristic peaks were identified; The linear range of β-eudesmol was 20.00 - 406.10 μg/mL (r = 0.999 9), and the average recovery was 100.75%, RSD = 1.17% (n = 6), and the limit of detection was 0.12 ng. The linear range of atractylon was 35.00 - 348.70 μg/mL (r = 0.999 5), and the average recovery was 99.84%, RSD = 1.29% (n = 6), and the limit of detection was 0.04 ng; The linear range of atractylodin was 16.46 - 329.30 μg/mL (r = 0.999 6), and the average recovery was 100.12%, RSD = 0.88% (n = 6), and the limit of detection was 0.06 ng. Conclusion: The concent determination and characteristic spectrum method of atractylodin, atractylon, and β-eudesmol established by this study are sensitive, simple, stability, which could make the determination result accurate and reliable.
