Article abstract of DOI:10.1016/0031-9422(91)85055-5

Two new norcarotenoids named trihydroxy-β-ionone and sec-hydroxyaeginetic acid, together with three known compounds, have been isolated from the steamed roots of Rehmannia glutinosa var. hueichingensis.Their structures were determined by chemical and spectral studies, and confirmed by X-ray analysis of trihydroxy-β-ionone acetate.
