Abstract | ETHNOPARMACOLOGICAL RELEVANCE: MATERIALS AND METHODS: The air dried fruit of Cornus officinalis was extracted in 80% EtOH, the obtained residue was fractioned on D101 resin column eluted with H2O/EtOH solution to get five crude fractions (fr. A-E). The anti- diabetic nephropathy activity of fractions (fr. A-E) was evaluated in vitro by inhibiting the expression of collagen IV (Col V), fibronectin (FN) and IL-6 in high- glucose-induced mesangial cells. By preliminary bio-assay screenings, repeated column chromatography on fraction B-D led the isolation of 22 compounds, whose structures were determined by extensive spectroscopic analysis, and the anti- diabetic nephropathy activity of the isolated compounds was also evaluated. RESULTS: Two new iridoid glucosides, logmalicids A and B (1 and 2), together with 20 known compounds (3-22) were isolated from the extract of Shanzhuyu under the bioassay-guided screenings. The anti- diabetic nephropathy activity assay displayed that fractions A, D and E could significantly inhibit the production of Col IV; fractions A and C could significantly inhibit the expression of FN and IL-6 in the high- glucose-stimulated mesangial cells at concentration of 50 μg/mL; and loganin (3) and its derivatives (1 and 2) could significantly inhibit the expression of FN and IL-6 at concentration of 10 μM, respectively.
