Description:
Three new triterpenoid derivatives, named (15 α )-15-hydroxysoyasapogenol B ( 1 ), (7 β ,15 α )-7,15-dihydroxysoyasapogenol B ( 2 ), and (7 β )-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.
