Bharangin isolated from the hexane extract of the root nodules of the Ayurvedic drug.Pygmacopremna herbacea (Roxb.) Moldenke. (Verbenaceae) has been shown to be a novel diterpenoid quinonemethide incorporating a δ-lactone moiety (3) and possessing (S) configuration at the chiral carbon atom from a consideration of its mass spectrum, UV, IR, 1H NMR and 13C spectra, 2D NMR INADEQUATE and CD spectrum. (3) appears to be derived biogenetically from a hypothetical diterpenoid skeleton designated as pygmane(4).
