Chemotaxonomy of Gonospermum and related genera

open access: yesPhytochemistry, 2010
Aerial parts of Gonospermum fruticosum collected at several locations in the Canary Islands afforded, in addition to known compounds, four sesquiterpene alcohols related to costol and a sesquiterpene lactone, whose structures were established on the basis of their spectroscopic data and chemical transformations. Except for Gonospermum species collected

Chemotaxonomy of the Rabdosia in Japan by Diterpenoids

open access: yesYAKUGAKU ZASSHI, 1998
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.
