A new cerebroside and its anti-proliferation effect on VSMCs from the radix of Cyperus rotundus L.

A new cerebroside, 1-O-(β-d-glucopyranosyloxy)-(2S,3R,4E,8Z)-2-[(2′R)-2′-hydroxylignoceranoylamino]-4,8-tetradecene-3-diol was isolated from the 60% EtOH extract of traditional Chinese medical plant Cyperus rotundus L. Its structure was determined on the basis of spectroscopic data. This new compound showed anti-proliferation effect on vascular smooth muscle cells (VSMCs).
