Objective: To elucidate the constituentes from the whole plant of Elephantopus scaber and to provide samples for activity screening. Method: The chromatography on silica gel was used and the structures were determined by IR

NMR and MS spectra analysis and physicochemical properties comparison. Result: Eight compounds were isolated and identified as 3

4-dihydroxy benzaldehyde(1)

p -coumaric acid(2)

vanillic acid(3)

syringic acid(4)

β -stitosterol(5)

daucosterol(6)

2

5-dimethoxy-1

4-benzoquinone(7)

n- octacosanoic acid(8). Conclusion: The compounds 1

3

5

7 and 8 were isolated from the plant scaber for the first time.
