From the stem bark of Pteleopsis hylodendron, a triterpenoidal saponin bellericagenin {B 3-O-[beta-D-glucopyranosyl-(1 -> 2)-alpha-D-glucopyranoside] (1) (Pteleopsoside)} and two sphingolipids, hylodendroside-I (2), and hylodendroside-II (3) were isolated, along with a synthetically known compound, {2 alpha, 3 beta, 23-triacetoxy-19 alpha-hydroxyolean-12-en-28-oic acid (4)}. Other known compounds, friedelin (5), P-carotene (6), lupeol (7), sitosterol (8), and stigmasterol (9), were also obtained. Their structures were deduced with the help of detailed spectroscopic studies. (C) 2008 Elsevier Ltd. All rights reserved.
