A chemical investigation of the endemic relict shrub Tetraena mongolica led to the isolation of four new triterpenes: 11α,12α:13β,28-diepoxyoleanane-3β-yl trans-caffeate (1), 3β-hydroxy-11α,12α-epoxyoleanane-28-al (2), olean-11-en-28-al-3β-yl trans-caffeate (3), and 28-acetoxy-olean-12-en-3β-yl trans-caffeate (4). Their structures were elucidated by extensive spectroscopic methods.
