ABSTRACT
The chemical constituents from ethyl acetate extract of Gleditsiae spina were isolated and purified by various chromatographic methods such as MCI gel CHP-20, ODS, Sephadex LH-20, silica gel and semi-preparative HPLC. Seven lignans were isolated and identified by spectroscopic data analyses as (7R,8S,7'E,7''S,8''R)-buddlenol P (1), (+)-syringaresinol (2), (+)-isolariciresinol (3), (7S,8R)-cedrusin (4), (7S,8R)-4,9,9'-trihydroxy-3,3'-dimethoxy-7,8-dihydrobenzofuran-1'-propylneolignan (5), 3',4-O-dimethylcedrusin (6), balanophonin (7). Among them, compound 1 is a new lignan, compounds 2-7 are isolated from the Gleditsia L. for the first time. MTT method was used to investigate the effect of compounds 2-7 on LPS-induced injury of NRK-52e cells. As a result, compounds 2, 3 and 7 exhibit protective effects against LPS-induced damage to NRK-52e cells.
