Abstract: Abstract Four new ent-kaurane diterpenes with chiral epoxyangelate moieties, (2′R,3′R)-3α-(2′,3′-epoxyangeloyloxy)-kaur-16-en-19-oic acid (1), (2′S,3′S)-3α-(2′,3′-epoxyangeloyloxy)-kaur-16-en-19-oic acid (2), (2′S,3′R)-3α-(2′,3′-epoxyangeloyloxy)-kaur-16-en-19-oic acid (3) and (2′R,3′S)-3α-(2′,3′-epoxyangeloyloxy)-kaur-16-en-19-oic acid (4), along with eight known diterpenes (5−12), were isolated from Wedelia prostrata.
