[Objective]To purify and identify the allelopathic substances from Artemisia annua extract.[Methods]The experiment used purified water as a solvent to extract chemical components from the roots,stems,and leaves of Artemisia annua,and quantitatively determined the acidic,neutral,and alkaline components using GC-MS.[Results]Different substances were detected in different parts of Artemisia annua extract,among which 38 acidic components were detected,roots contained the most types(20 types);There were 21 neutral components,stems contained the most types(10 types);There were 21 alkaline components,leaves contained the most types(9 types).The roots and stems contain a significant amount of organic acids and alkenes,such as 5-(1-methylethylene)-1,3-cyclopentadiene,2,3-dioxodiacetylbutyronitrile,and cisbicyclo[4.2.0]octan-3,7-diene.[Conclusion]The roots and stems of Artemisia annua may be the main sites for the production of allelopathic substances,with products mostly consisting of organic acids and alkenes.
