A benzoxepine derivative from Delphinium formosum

1996    Mericli, F; Mericli, AH; Becker, H; Ulubelen, A

From an ethanolic extract of Delphinium formosum, in addition to a group C-19 alkaloids, a new benzoxepine derivative was isolated, whose structure was elucidated by spectral data, including 1D and 2D NMR techniques, as 1,1',7-trimethyl-2-oxo-3,8-dihydroxy-6-methoxy-benztetrahydrooxepine.
