Rhazya stricta Decaisne (Apocynaceae) (1), locally known as “Sehar” (2), is a small glabrous shrub widely used in indigenous medicine for treatment of various diseases (3-5); it has been shown to possess antitumor properties, as well (6,7). As a result of our investigations on the alcoholic extracts of the dried legumes (without seeds) of R. stricta, we have isolated an alkaloid that has not been reported previously from this plant. © 1984, American Chemical Society.
