Abstract
Two new dammarane-type triterpenes, cordialin A and B, isolated from Cordia verbenacea have been identified. They have in common a 3,19-hemiacetal group bridging ring A, and an 11α-hydroxy-group. They differ in the substitution pattern of the side-chain, the former having a 20(22)en-23-one system and a 24,25-epoxide group, while the latter bears a 20(22)-ene-24,25-diol system.Keywords
