Evaluation and Analysis of Inorganic Elements in Different Origins of Fructus Arctii by Microwave Digestion-ICP-AES
Objective: To determine the inorganic elements of 20 batches of Fructus Arctii by microwave digestion-ICP-AES. Method: Samples were digested by nitric acid and hydrogen peroxide. The content of 26 elements in Fructus Arctii was determined by ICP-AES
a blank experiment was made at the same time. Principal component analysis (PCA) was used to evaluate the quality of different batches of Fructus Arctii. Result: Fructus Arctii contained more than 12 inorganic elements and the content of six elements
including K
Al
Fe
S
Zn
Cu was higher. PCA with four factors (F1
F2
F3
F4) selected could be used to evaluate the quality of Fructus Arctii. The function was following F=0.298 74F1+0.257 56F2+0.144 49F3+0.135 19F4.The samples from Zhejiang
Hebei and Jilin provinces were the top three which indicated the quality in those regions were better based on inorganic elements. Conclusion: This method is fast
simple and accurate. All the results can provide a scientific basis for the quality analysis and comprehensive utilization of Fructus Arctii.
