Abstract Four new euphane triterpenes, (3 β )‐3‐(acetyloxy)eupha‐7,25‐dien‐24‐one ( 1 ), (3 β ,24 R )‐3‐(acetyloxy)eupha‐7,25‐dien‐24‐ol ( 2 ), (3 β ,24 S )‐eupha‐7,25‐diene‐3,24‐diol ( 3 ), and (3 β ,24 R )‐eupha‐7,25‐diene‐3,24‐diol ( 4 ) were isolated from the barks of Broussonetia papyrifera , a tree whose roots, barks, and fruits were used as herbal drugs in China. The structures of 1 – 4 were elucidated on the basis of spectroscopic evidence and chemical methods.
