Abstract:
Objective To evaluate the quality of Hedysari Radix from different producing areas in Gansu Province by setting Hedysari Radix from different producing areas in Gansu Province as study subjects and trace elements in Hedysari Radix as evaluation indexes; To provide the references for establishment of the quality standards of Hedysari Radix.Methods The content of Fe, Cu, Ca, Mn, Zn, Mg, Cr, Co, Na, Li, Ni and K in Hedysari Radix were detected by using flame atomic absorbption method. Data were analyzed by the factor analysis conducted by SPSS21.0 software. The common factors were extracted by principal component and analytic function for quality comprehensive ranking was established.ResultsThree common factors were extracted, namely F1, F2, and F3. The quality function was Y=0.657F1+0.119F2+0.089F3. Cr, Li, Co, Cu, Zn, Fe and Mg were the characteristic trace elements of Hedysari Radix that could affect the quality of Hedysari Radix. When the quality of Hedysari Radix was evaluated by the contents of trace elements, the quality of wild Hedysari Radix were better than cultivated Hedysari Radix and the quality rank was consistent with the idea that Longnan is the main producing area of Hedysari Radix. The quality of samples from Dingxi area was better.Conclusion The quality evaluation of Hedysari Radix based on trace elements shows the differences in Hedysari Radix from different producing areas in Gansu Province and the results are relatively reasonable.
