Two new indole alkaloids from Vinca herbacea L.[Reference: WebLink]
Six indole alkaloids were isolated from the aerial parts of Vinca herbacea Waldst. et Kit.
METHODS AND RESULTS:
Structures of the isolated compounds were elucidated as two new alkaloids, 10-methoxyraucaffrinoline (1) and 11-methoxyburnamine (2), and four known alkaloids, picrinine (3), burnamine (4), Caboxine A (5) and elegantine (6) by intensive 1D- and 2D-NMR spectroscopic techniques.

Structure des caboxines: Alcaloïdes oxindoliques du Cabucala fasciculata[Reference: WebLink]

METHODS AND RESULTS:
The structures of three new 11-monomethoxy pentacyclic oxindole alkaloids have been elucidated by chemical correlations with reserpinine: Caboxine A was assigned to the allo C19-méthyl α series: 3S, 4R, 7S, 19S; isocaboxine-A and B to the epi-allo C19-methyl α series and have, respectively, the following configurations 3R, 4S, 7S, 19S and 3R, 4S, 7R, 19S.
