Abstract

From the leaves of a Thai medicinal plant, Croton sublyratus, collected in Thailand, two new cembrane-type diterpenoids, named sublylactones A and B, and a phenolic compound were isolated from the EtOAc-soluble fraction of a MeOH extract. Their structures were elucidated on the basis of spectroscopic evidence.
