Two new dihydroindole alkaloids were isolated from Rauwolfia vomitoria Afz. One of them proved to be sandwicine, previously isolated from Rauwolfia sandwicensis. The structure of isosandwicine was assigned to the other substance on the basis of its spectroscopic and chemical properties and by correlation with sandwicine and ajmaline.

Abstract
Two new dihydroindole alkaloids were isolated from Rauwolfia vomitoria Afz. One of them proved to be sandwicine, previously isolated from Rauwolfia sandwicensis. The structure of isosandwicine was assigned to the other substance on the basis of its spectroscopic and chemical properties and by correlation with sandwicine and ajmaline.
