From Arisaema amurense, four new cerebrosides were isolated along with a known cerebroside. The new cerebrosides were characterized as 1-O-beta-D-glucopyranosyl- (2S,3R,4E,8Z)-2-[(2(R)- hydroxyicosanoyl)amido]-4,8-octadecadiene-1,3-diol (1), 1-O-beta-D- glucopyranosyl-(2S,3R,4E,8Z)- 2-[(2-hydroxyoctadecanoyl)amido]-4,8-octadecadiene-1,3-diol (2), 1-O-beta-D- glucopyranosyl- (2S,3R,4E,8E)-2-[(2-hydroxyicosanoyl)amido]-4,8-oct adecadiene-1,3-diol (4), and 1-O-beta-D- glucopyranosyl-(2S,3R,4E,8E)-2-[(2-hydroxyoctadecanoyl )amido]-4,8- octadecadiene-1,3-diol (5), respectively. These cerebrosides displayed significant antihepatotoxic activity.
