摘要
A new monoglyceride, 1%26apos;,26%26apos;-bis-[(S)-2,3-dihydroxypropyl] hexacosanedioate (la) and the new peltogynoid, entadanin (3), along with eight known compounds, were isolated from the stem bark of Entada abyssinica (Fabaceae). The structures of the new compounds were determined by detailed analyses of ID and 2D NMR. spectra, in combination with high-resolution mass spectrometry data, and by comparison with related data from the literature. The stereochemistry of la was derived by comparison of the optical rotation with reference data. Peltogynoids have been reported previously from other Fabaceae, however this is the first report of a peltogynoid from the genus Entada.
