Abstract: GC-MS fingerprint of the volatile chemical constituents in Artemisia capillaris herba was built,and orthogonal projection resolution was adopted for the extraction of common peaks from different sources of Artemisia capillaris herba.The criteria of common peak rate,variance coefficient and similarity were adopted for the evaluation of four different Artemisia capillaris herba samples from Hebei,Gansu,Shandong and Hunan provinces respectively,the chemical pattern characters of the volatile chemical constituents in Artemisia capillaris herba were characterized comprehensively from commonness,diversity and integrity.It showed a fair consistency in their GC-MS fingerprints among Artemisia capillaris herba samples from different sources.Artemisia capillaris herba was distinguished from Artemisia sacrorum L., a possible substitute in traditional Chinese medicine,by comparing the fingerprints with each other.

Key words: Artemisia capillaris herba, Fingerprint, Orthogonal projection resolution, Common peaks rate, Variance coefficient, Similarity
