Abstract: Seven compounds were isolated from the alcohol extract of Edgeworthia gardneri by various technologies, including silica gel, Sephadex LH-20 and high performance liquid chromatography, and were identified as edgeworthiaside A (1), 2,4,6-trichlorol-3-methyl-5-methoxy-phenol 1-O-β-D-glucopyranosyl-(1-6)-β-D-glucopyranoside (2), 2,6-dimethoxy-4-(2-propen-1-yl)phenyl 6-O-(6-deoxy-α-L-mannopyranosyl)-β-D-glucopyranoside (3), eugenol rutinoside (4), tiliroside (5), edgeworoside C (6), and salicylic acid (7). Compound 1 is a new chlorophenyl glycoside and 2-4 were isolated for the first time from Edgeworthia gardneri. The in vitro inhibition of α-glucosidase showed that the inhibition rate of compounds 1 and 2 were similar to acarbose.
