Abstract: To investigate the chemical constituents of C.incana (Thunb.)Miq.The compounds were isolated with Sephadex LH-20,silica gel column chromatography.The structures of compounds were identified on the basis of physiochemical properties and spectral data.Ten compounds were isolated and identified as vanillic acid(1),protocatechuic acid(2),p-hydroxyphenylethyl alcohol(3),luteolin(4),lariciresinol(5),lariciresinol-4-O-β-D-glucopyranoside(6),lariciresinol-9-O-β-D-glucopyranoside(7), β-sitosterol(8),Stearic acid(9),daucosterol(10).All compounds were isolated from this plant for the first time.

Key words: Verbenaeeae, C.incana (Thunb.)Miq, chemical constituents, structure identification
