A New Ceramide Isolated from Ficus lutea Vahl (Moraceae).

In addition to benjaminamide (2), β-amyrin, β-amyrin acetate, lupeol, betulinic acid, β-sitosterol glucoside, a new ceramide glycoside was isolated from the woods of Ficus lutea Vahl (Moraceae). Using mass fragmentation pattern, 1 and 2D NMR spectra and by comparison with published data, the new compound was characterized as 1-O-β-D-glucopyranosyl-(2S,3R,5E,12E)-2N-[(2'R)-hydroxyhexadecanoyl]-octadecasphinga-5,12-dienine (1a) for which the trivial name lutaoside was proposed. Some isolated compounds were evaluated for their antimicrobial activities. Compounds 1a and 2 showed some antimicrobial activity.
