Abstract
A new rotenoid analogue, boeravinone C, has been isolated from the root of (Boerhaavia)___- (diffusa)___- Linn (Nyctaginaceae) and its structure has been determined by means of 2-D NMR. The 1H-NMR of boeravinone C showed unusual splitting patterns due to ABC spin systems. These splitting patterns were analyzed by simulation.
