Abstract Two new compounds, 1‐(3‐methoxy‐4‐hydroxyphenyl)‐3‐(3, 5‐dimethoxy‐4‐hydroxyphenyl)‐propane (1) and 5, 7, 3′‐trimethyoxyflavan‐4′‐O‐β‐ D ‐glucopyranoside (2) were isolated from the ethanol extract of the dried aerial parts of Phacellaria compressa Benth., together with 2,3‐bis[(4‐hydroxy‐3,5‐dimethoxyphenyl)‐methyl]‐1,4‐butanediol (3), ethyl 3,4,5‐trihydroxybenzoate (4), methyl 3, 4, 5‐trihydroxybenzoate (5), β‐sitosterol (6), 5, 7, 3′, 4′‐tetrahydroxyflavan (7), lupeol (8), zhebeiresinol (9), quercetin‐3‐O‐α‐ L ‐rhamnopyranoside (10), (+)‐catechin (11), betulin (12), β‐daucosterol (13), (+)‐syringaresinol (14), scopoletin (15), and proximadiol (16). The structures of these compounds were determined by spectral evidence or by comparing them with authentic samples. Compound 9 showed α‐amylase inhibitory activity of 57.55% at a concentration of 50 μg/mL. (Managing editor: Wei Wang)
