Chemical constituents from the stem bark of and their SREBP-1c inhibitory activity.

One new lignan, julibrissinoside II, along with thirteen known compounds, was isolated from the stem bark of . The structure of julibrissinoside II was determined on the basis of extensive spectroscopic methods, including NMR and CD spectroscopic data. The isolated compounds were tested for their SREBP-1c inhibitory activity at different concentrations using mouse hepatocyte AML12 cell lines. Among them, linoleic acid () and 3--methylfisetin () showed significant SREBP-1c inhibitory activity at the concentration of 100 µM.
