Abstract: A new ent-kaurane diterpenoid , dipterinoid A (1 ) , was isolated from the aerial parts of Dipteris chinensis together with thirteen known compounds . Its structure was determined as 16β-hydroxy-17- [ ( Z) -p- coumaroyl ]- ent-kauran-19-oic acid by extensive NMR and MS analysis. All of known compounds were isolated from this plant for the first time.
