Abstract:
The new cerebroside 1-O-(β-D-glucopyranosyl)-(2S, 3S, 4R, 8E)-2-[(2'R)-2'-hydroxytetracosenoilamino]-8-octadecene-1,3,4-triol (1) and ceramide (2S, 3S, 4R, 8E)-2-[(2'R)-2'-hydroxytetracosenoilamino]-8-octadecene-1,3,4-triol (2) were isolated from the ethyl acetate extract of the pollen of Brassica napus L. The structures of 1 and 2 were elucidated on the basis of chemical and spectroscopic method. Two new compounds were evaluated for activity in vitro assays for the cytotoxic activities against human tongue squamous carcinoma cell line (Tca8113).
