Abstract:

Aim To compare the chemical constituents of Artemisia borealis with three other Artemisia plants which are generally used in traditional Chinese medicine. Method The chemical components of essential oil from the leaves of A. borealis were analyzed by GC- MS and the chemical components of water extracts of the four plants were compared by HPLC fingerprint method. Conclusion From the essential oil of A. borealis, 52 peaks were separate, 48 of them were identified by GC-MS analysis, indicative that aromadendrane-4-ol is the highest constituent, which made up 24.73% of the total essential oil. In addition the chief constituents of the leaves of A.borealis are similar to the three other plants but its pattern of HPLC fingerprint is different. The content of chlorogenic acid in aerial part of A. annus and A. scapillaries, leaves of A. borealis and A. argyi are 0.065, 0.192, 0.617and 0.178 % respectively.
