Objective: To establish a method for determining five flavonoids in Artemisia frigida in order to review the collection time. Method: The content of five flavonoids in different collection time and parts of A. frigida was determined by HPCE and the content was compared to predicate the collection time. Result: The linear ranges of five flavonoids were 1.00-40.00 mg·L-1 (r=0.999 8)
2.00-80.00 mg·L-1 (r=0.999 9)
0.50-80.00 mg·L-1 (r=0.999 6)
1.00-40.00 mg·L-1 (r=0.999 3) and 1.00-40.00 mg·L-1 (r=0.999 4) respectively. The average recoveries of five flavonoids were 99.31% (RSD 1.60%)
98.14% (RSD 1.03%)
98.37% (RSD 1.57%)
97.92% (RSD 0.94%)
98.16% (RSD 1.20%). Conclusion: The content of five flavonoids in the flower is more than that in other parts. The optimal collection time is from the middle of June to the end of July.
