- Two new C19-diterpenoid alkaloids from Aconitum nagarum var. lasiandrum
-
Further investigation on the phytochemistry of the plant Aconitum nagarum var. lasiandrum led to isolate two C19-diterpenoid alkaloids, francheline (1) and lasianine (3). Their structures were established on the basis of the spectral data.

- THE STRUCTURES OF FOUR NEW C19-DITERPENOID ALKALOIDS FROM ACONITUM FORRESTII STAPF
-
From the root extracts of Aconitum forrestii Stapf, we have isolated four new alkaloids: acoforine (6), acoforesticine (8), acoforestine (10) and acoforestinine (14), besides crassicauline A, forestine and yunaconitine.The structures of these alkaloids were determined on the basis of spectral data and correlation with alkaloids of established structures.The structure and stereochemistry of acoforestine (10) was confirmed by an X-ray crystal structure determination.
