摘 要:Two new compounds, 1-(3-methoxy-4-hydroxyphenyl)-3-(3,5-dimethoxy-4-hydroxyphenyl)-propane (1) and 5, 7, 3'-trlmethyoxyflavan-4'-O-β-D-glucopyranoslde (2) were Isolated from the ethanol extract of the dried aerial parts of Phacellarla compressa Benth., together with 2,3-bis[(4-hydroxy-3,5-dimethoxyphenyl)-methyl]-1,4- butanedlol (3), ethyl 3,4,5-trlhydroxybenzoate (4), methyl 3, 4, 5-trlhydroxybenzoete (5), β-sltoeterol (6), 5, 7, 3', 4'- tetrahydroxyfiavan (7), lupeol (8), zhebelreslnol (9), quercetln-3-O-α-L-rhamnopyranoslde (10), (+)-cetechin (11), betulln (12), β-daucosterol (13), (+)-sydngareslnol (14), scopoletln (15), and proxlmadlol (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.Two new compounds, 1-(3-methoxy-4-hydroxyphenyl)-3-(3,5-dimethoxy-4-hydroxyphenyl)-propane (1) and 5, 7, 3'-trlmethyoxyflavan-4'-O-β-D-glucopyranoslde (2) were Isolated from the ethanol extract of the dried aerial parts of Phacellarla compressa Benth., together with 2,3-bis[(4-hydroxy-3,5-dimethoxyphenyl)-methyl]-1,4- butanedlol (3), ethyl 3,4,5-trlhydroxybenzoate (4), methyl 3, 4, 5-trlhydroxybenzoete (5), β-sltoeterol (6), 5, 7, 3', 4'- tetrahydroxyfiavan (7), lupeol (8), zhebelreslnol (9), quercetln-3-O-α-L-rhamnopyranoslde (10), (+)-cetechin (11), betulln (12), β-daucosterol (13), (+)-sydngareslnol (14), scopoletln (15), and proxlmadlol (16).
