title: [Alkaloids of the Annonaceae: composition of the bark of the trunk and roots of Enantia pilosa].
abstract: The alkaloidal content of stem- and root-bark of Enantia pilosa Exell (Annonaceae) was studied and compared to that of other Enantia spp. Six aporphine alkaloids were isolated; two alkaloids, oliverine and oliveridine, were found in major amounts; two oxoaporphines, liriodenine and lanuginosine, were present; two other alkaloids, N-oxyoliverine and N-oxyoliveridine, were isolated for the first time. Quaternary alkaloids from stem-bark are presently under investigation.
