Abstract: To determine the effects of feed intake and trample damage on secondary metabolites of Artemisia frigida, A. frigida from Inner Mongolia grassland was potted in the laboratory and treated with different degrees of mechanical damage (light, moderate, severe, and a control group without damage). Then chemical components of the leaves were analyzed by gas chromatography/mass spectrometry (GC-MS). Results showed that with mechanical damage treatment the total amount of secondary metabolites increased within a certain time range. Secondary metabolites with light damage increased gradually and peaked at 24 h; moderate and severe treatments increased rapidly, peaked at 6 h, and then declined. Increases in species of secondary metabolites were visible when treated with light and moderate damage, but a decrease appeared with severe damage. The main components of secondary metabolites were terpenoids which accounted for more than 80% of the total. The terpenoid content when compared with the control increased 59% with light damage, 54% with moderate damage, and 67% with heavy damage. The increase of 8-hydroxylinalool was greatest; however, phenols, alcohols, aromatics, and ketones also increased. [Ch, 5 fig. 1 tab. 23 ref.]
