Abstract From the aerial parts of Vinca sardoa , seven indole alkaloids were isolated, conoflorine and six plumerane-type indolines, N (1)-methyl-14,15-didehydro-12-hydroxyaspidofractinine, N (1)-methyl-14,15-didehydro-12-methoxyaspidofractinine, N (1)-formyl-14,15-didehydroaspidofractinine, N (1)-formyl-14,15-didehydro-12-hydroxyaspidofractinine and the known, venalstonine and N (1)-methyl-14,15-didehydroaspidofractinine.
