Abstract

Abstract: Two new dammarane-type triterpenoids, dammar-3 α, 12( R ), 20( S )-triol-12, 32( R );20, 32-diepoxy-25-methy-25-en-tridecacyclic ether (1 ) and (23 E )-12 β, 20( R ), 25( S ), 26-tetrahydroxydammar-23-en-3-one (2 ) were isolated from the green walnut husks of Juglans mandshurica Maxim together with six known compounds. Their structures were elucidated through extensive spectroscopic analyses and by comparison with the literature, and the cytotoxic activities of these compounds were evaluated. Graphical Abstract:
