Abstract
Seven new β-amyrin derived oleanane-type triterpene coumaroyl esters were isolated from the twigs and leaves of Casuarina equisetifolia, together with two known triterpenoids, erythrodiol and oleanolic acid, and a number of benzoic acid derivatives. The structures of the seven new compounds have been elucidated as 3-O-(E)-coumaroyl β-amyrin, 3-O-(Z)-coumaroyl β-amyrin, 3-O-dihydrocoumaroyl β-amyrin, 3-O-(E)-coumaroyl erythrodiol, 3-O-(Z)-coumaroyl erythrodiol, 3-O-(E)-coumaroyl oleanolic acid and 3-O-(Z)-coumaroyl oleanolic acid by spectroscopic analyses and chemical degradation. Evaluation of the antioxidant activities of the isolated compounds indicates that gallic acid is one of the antioxidant substances present in C. equisetifolia.
