Abstract: Thirteen compounds were isolated from the ethanol extract of the aerial part of Inula lineariifolia Turcz.. On the basis of spectral analysis and comparison with the relative literatures, their structures were identified respectively as eupatin (1), spinacetin (2), hispidulin (3), daucosterol (4), β-sitosterol (5), α-spinasterol (6), taraxasteryl acetate (7), (+)-syringaresinol (8), dehydrovomifoli (9), 4-hydroxy-benzaldehyde(10), vanllin polymer (11), 4-hydroxy-3,5-dimethoxybenzaldehyde (12), and 4-hydroxy-2,6-dimethoxybenzaldehyde (13). All compounds were isolated from I. lineariifolia for the first time.
