THE ALKALOIDS OF FUMARIACEOUS PLANTS: XVI. SOME MISCELLANEOUS OBSERVATIONS

Abstract

Eleven new alkaloids are described. They have been obtained from mother liquors from plants whose investigation has already been reported. The present record deals with Dicentra cucullaria (three)*, D. eximia (four), Corydalis aurea (seven), and C. sempervirens (two). For convenient reference all new alkaloids in this series of communications have been given a number following the letter F, and a table is included in which the salient features are summarized.Alkaloid F 23 (formerly -η) has now been obtained from C. sempervirens. It is shown to be the optical antipode of d-adlumine, and a mixture of the two has yielded the dl-form.
