Antitumor Activity of Rabdosia and Teucrium Diterpenoids against P 388 Lymphocytic Leukemia in Mice

Abstract

A considerable antitumor activity of Rabdosia diterpenoids, oridonin (1), enmein (2), enmein-3-acetate (3), nodosin (4), and shikoccin (5), was recognized against P 388 lymphocytic leukemia inoculated into mice. Teucrium diterpenoids, teucvin (6) and teucvidin (7), did not show any activity. A brief discussion on the activity is also described.
