Pyrrolizidine alkaloids from Critonia morifolia

, 1998
Three pyrrolizidine alkaloids were isolated from Critonia morifolia and their structures elucidated by spectroscopic methods. Besides the already known rinderine and its O-12-acetylderivative, one with a new strucure was found. For this alkaloid (O-9-(+)-

The synthesis of pyrrolizidine alkaloids

, 1982
The pyrrolizidine alkaloids constitute an exceptionally large class of naturally occurring compounds. A number of the alkaloids are hepatotoxic and carcinogenic, but some derivatives have potentially useful physiological properties;A promising but seldom

Dietary alkaloids and the development of androconial organs in Estigmene acrea

Journal of Insect Science, 2003
Male salt marsh moths, Estigmene acrea (Lepidoptera: Arctiidae), possess inflatable androconial organs called coremata. Prior to mating males form aggregations and inflate their coremata en masse.
