Three new lipids from the seeds of Trogopterus xanthipes

Chemical investigation of Feces Trogopterus (Trogopterus xanthipes) has led to the isolation of three new lipids, including two new cerebrosides, 1-O-(β-D-glucopyranosyloxy)-(2S,3S,4R,6E)-2-[(2'R)-2'-hydroxyheptadecanoylamino]-8-heptadecene-3,4-diol (1) and 1-0-(β-D- glucopyranosyloxy)-(2S,3S,4R,6E)-2-[(2'R)-2'-hydroxy-heptadecanoylamino]-8-nonadecene-3,4-diol (2), and one new fatty acid ester, bis(2,3-dihydoxypropyl)-tetracosanedioate (3). Their structures were elucidated by chemical and spectral means. This is the first report on the occurrence of cerebroside and fatty diacid diester in Feces Trogopterus.
