Abstract:From the jeaves of Rabdosia nervosa (Hemsl.) C. Y. WU et H. W. Li (Labiatae), a new diterpenoid nervosin (II) was isolated and the structure was established by spectroscopic evidence. One known diterpenoid, odonicin, was also isolated together with an other new diterpenoid (will be published elsewhere).
