Abstract:
Four oleanane-type triterpenes, 3alpha,21beta,22alpha-trihydroxy-11,13(18)-oleanadien-28-oic acid (1), 3-epi-papyriogenin C (2), 21-O-acetyl-21-hydroxy-3-oxo-11,13(18)-oleanadien-28-oic acid (3) and 3beta-hydroxy-21-oxo-11,13(18)-oleanadien-28-oic acid methyl ester (4), together with four known triterpenes, were isolated from Tetrapanax papyriferus (Hook) K. Koch. Papyriogenin A (8) exhibited anti-HIV activity and low cytotoxicity in acutely infected H9 lymphocytes. Their structures were determined by analysis of spectroscopic data, including by 1D and 2D NMR.
