Abstract

Three new pentacyclic triterpenoid esters 1–3 together with six known lupane-type triterpenoids were isolated from Bruguiera cylindrica. The structures of the new compounds were elucidated by spectroscopic methods and were characterized as 3α-E-coumaroyllupeol 1, 3α-Z-coumaroyllupeol 2, and 3α-E-caffeoyltaraxerol 3.
