Oleanane-type triterpenes from the flowers, pith, leaves, and fruit of Tetrapanax papyriferus

Oleanane-type triterpenes were isolated from Tetrapanax papyriferus (Hook) K. Koch, whose structures were determined by analysis of spectroscopic data, including by 1D and 2D NMR. Papyriogenin A (8) exhibited anti-HIV activity and low cytotoxicity in acutely infected H9 lymphocytes.
