摘要：

Two new saponins, 2 alpha, 3 alpha,19 alpha,23-tetrahydroxyolean-12-en-28-O-beta-D-galactoside, and sitesterol alpha(1 -->3) diglucoside, were isolated from the stem barks of Pteleopsis hylodendron along with a known triterpenoid, 2 alpha,3 beta,21 beta,23-tetrahydroxyolean-12-en-28-oic acid, which was isolated for the first time from this plant. The structures of these compounds were elucidated with the help of spectroscopic studies. (C) 1999 Elsevier Science Ltd. All rights reserved.
