Abstract

Rhinacanthin-A and -B, two new naphthoquinones, and the known lupeol, β-sitosterol, stigmasterol, as well as the glucosides of β-sitosterol and stigmasterol were isolated from the roots of Rhinacanthus nasutus. The structures of rhinacanthin-A and -B were elucidated on the basis of spectral analyses. Rhinacanthin-B demonstrated significant Cytotoxicity (ED50 = 3.0μg/ ml) in the KB tissue culture cell.
