NAPHTHOQUINONES FROM DIONAEA MUSCIPULA

Article abstract of DOI:10.1016/0031-9422(90)85125-Y

Beside the known naphthoquinone, plumbagin, the new compound hydroplumbagin 4-O-β-glucopyranoside has been isolated from a methanolic extract of Dionaea muscipula, together with two known naphthoquinones, droserone and 3-chloroplumbagin which have not been reported previously from this plant.Structure determination of hydroplumbagin 4-O-glucoside was carried out unambiguously by NOE experiments.
