BOERAVINONE A AND B, NEW ROTENOID ANALOGUES FROM (BOERHAAVIA)___- (DIFFUSA)___- LINN

Abstract

Two new rotenoid analogues, boeravinone A and B, have been isolated from the roots of (Boerhaavia)___- (diffusa)___- Linn. (Nytaginaceae) and their structures have been determined based on the 2-D NMR spectroscopy including INADEQUATE and ¹H-¹³C long range COSY.KEYWORDS-(Boerhaavia)___- (diffusa)___-; Nyctaginaceae; rotenoid; boeravinone A; boeravinone B
