title: [Chemotaxonomy of the Rabdosia in Japan by diterpenoids].
abstract: Many diterpenoids containing mostly ent-kaurenoids have been isolated from the Rabdosia (Labiatae). The relation of the diterpenoids with its species in Japan has been studied. The ratio of diterpene types and the values of oxidation state in each plant were calculated. These species were found to be divided into four groups by the cluster analysis of the values of oxidation state of C-1 to C-20 in the diterpenoids of the Rabdosia.
