✦ Synopsis

Three new triterpenoid derivatives, named (15a)-15-hydroxysoyasapogenol B (1), (7b,15a)-7,15dihydroxysoyasapogenol B (2), and (7b)-7,29-dihydroxysoyasapogenol B (3), were isolated from cultures of the plant endophytic fungus Pestalotiopsis clavispora. Their structures and relative configurations were elucidated by extensive spectroscopic analysis and X-ray crystallography.
