Paullinoside A and paullinomide A: A new cerebroside and a new ceramide from leaves of Paullinia pinnata

Abstract

Paullinoside A (1a), a new cerebroside, and a new ceramide named paullinomide A (2a), have been isolated from Paullinia pinnata. Their structures were determined by comprehensive analyses of their 1D and 2D NMR, HREIMS spectral data, and chemical evidence. The remaining four known compounds were identified as β-amyrin, 13β,17β-dihydroxy-28-norolean-12-ene, β-sitosterol, and β-sitosterol glucopyranoside. © 2006 Verlag der Zeitschrift für Naturforschung.
