Outline
Eleven compounds were isolated from the ethyl acetate fraction of the 95% aqueous ethanol extract of the roots of Sophora tonkinensis by silica gel, ODS, Sephadex LH-20 column chromatography, and semi-preparative RP-HPLC. Their structures were identified as 7-hydroxy-8-isopentenylchromone (1), furo[2, 3-f]-1, 3-benzodioxole-7-carboxylic acid (2), 6-[3-(2′, 4′-dihydroxyphenyl)acryloyl]-7-hydroxy-2, 2-dimethyl-8-(3-methyl-2-butenyl)-2H-benzopyran (3), flemichapparin B (4), tectorigenin (5), genistein (6), 6-hydroxy-1, 3-benzodioxole-5-carboxylic acid (7), vanillic acid (8), protocatechuic acid (9), 2, 4-dihydroxybenzoic acid (10), and p-hydroxybenzoic acid (11) through extensive spectroscopic data (IR, UV, HR-ESI-MS, and NMR spectra). Among them, compounds 1 and 2 were new compounds. In addition, compound 3 showed significant α-glucosidase and protein tyrosine phosphatase-1B (PTP1B) inhibitory activities with IC50 values of 5.595 and 0.320 μmol·L-1, respectively.
