title: Iridoids from Spathodea campanulata P. Beauvais leaves.
abstract: Three new and four known iridoids have been isolated from the leaves of Spathodea campanulata, the structures of the new compounds were determined as 6-O-trans-caffeoyl-decinnamoyl globularimin, 6-O-trans-caffeoyl-asystasioside E and 6-O-trans-caffeoyl-5,7-bisdeoxycynanchoside and provisionally named as spatheosides A (1), B (2) and C (3) respectively. The known iridoids were identified as verminoside (4), 6'-O-trans-caffeoyl-loganic acid (5), catalpol (6) and ajugol (7). The structures of the isolated compounds were characterized by different spectroscopic methods.
