[One new galloyl derivative from Isodon henryi].

Seven compounds(1-7) were isolated from Isodon henryi through silica gel, Sephadex LH-20, ODS, MCI column chromatography and semi-preparative HPLC. Their structures were identified as isogallicacid(1), caffeic acid(2), syringic acid(3), protocatechuic acid(4), oresbiusin A(5), lophanthoside A(6), and 8-hydroxypinoresinol(7), by spectroscopic techniques including HR-MS, IR, UV, NMR, and ECD. Compound 1 was a new galloyl derivative. Moreover, it demonstrated a significant inhibitory effect on the lipopolysaccharide-induced release of nitric oxide from RAW264.7 cells.
