title: Pacovatinins A-C, new labdane diterpenoids from the seeds of Renealmia exaltata.
abstract: Three new labdane diterpenoids, pacovatinins A-C (1-3), were isolated from seeds of the Brazilian medicinal plant Renealmia exaltata ("Pacová-catinga"), and their structures including absolute configurations were elucidated by spectroscopic data and a modified Mosher method.
