Alkaloids from Garrya Species

DITERPENE ALKALOIDS FROM ACONITUM, DELPHINIUM, AND GARRYA SPECIES THE C -DITERPENE ALKALOIDS... 

Structural and synthetic studies of the diterpene alkaloids of the Aconitum, Delphinium, and Garrya species continue to provide more insight into the chemistry of these complex bases. In recent years Japanese workers have isolated a series of isoprenoid alkaloids from plants of Daphniphyllum macropodum Miquel. Structural work on four new alkaloids representing three new structural types has been reported during this year. 

Studies on the diterpenoid alkaloids published during the past twelve months have provided much new structural and synthetic information on these complex plant bases. Twenty diterpenoid bases that are new or previously undetected in plant material have been reported from Aconitum and Delphinium species, and from Consolida ambigua and Garrya ovata. An extensive review of diterpenoid alkaloid chemistry has been published. ...
