Lignan Diesters of Canangafruticoside A from the Leaves of Cananga odorata var. odorata

From the leaves of Cananga odorata var. odorata, three relatively large molecules, namely two aryl naphthalene lignan diesters of canangafruticoside A and one cyclobutane lignan diester of canangafruticoside A, were isolated along with four known compounds. The structures of the new compounds were elucidated based on spectroscopic evidence.
