Acetylated aporphine alkaloids from Lysichiton camtschatcense.
Two N,O-diacetylaporphine alkaloids, N,O-diacetylnoroliveroline (1) and N,O-diacetyl-(-)-nornuciferidine (2), have been isolated and characterized from the rhizomes of Lysichiton camtschatcense. Their structures were determined by spectroscopic data analysis. DPPH (2,2-diphenyl-1-picrylhydrazyl) radicals were scavenged by compounds 1 and 2, but with weak activity.
