摘要： The chemical constituents of leaf oils of Elephantopus scaber L from 12 locations in Southern China, including three provinces and Hong Kong, were investigated using GC/MS. A total of 24 compounds were detected, of which 20 were identified by their mass spectra fragmentation patterns. The major compounds include hexadecanoic acid (8.19-39.22%), octadecadienoic acid (trace - 29.22%), five alkane homologues, i.e., n-tetradecane (1.19-5.26%), n-pentadecane (3.22-12.05%), n-hexadecane (2.38-16.26%), n-heptadecane (2.48-15.32%), and n-octadecane (1.39-9.59%), as well as tetramethylhexadecenol (2.06-4.31%). Hierarchical cluster analysis classified the leaf oils into two groups. Two main chemotypes of leaf oils in E. scaber were thus identified, one rich in hexadecanoic acid and octadecadienoic acid, and the other rich in the five alkane homologues.
