Two novel highly oxygenated and one rare B-ring cleave ent-kaurane diterpene glucosides, named prinsoside A (1), B (2) and C (3), respectively, were isolated from an ethanolic extract of the seeds of Prinsepia utilis. To our knowledge, prinsoside B (2) was the most highly oxygenated ent-kaurane diterpene glucoside discovered in nature. Their structures were elucidated by various spectroscopic meth ...
