Dendrobium gibsonii, an Orchidaceae plant yielded the first natural fluorenone derivatives designated dengibsin and dengibsinin to which 1,5-dihydroxy-7-methoxy-9-fluorenone (1) and 1,6-dihydroxy-5,7-dimethoxy-9-fluorenone (2) structures have been assigned respectively.The structures are fully supported by the 1H-NMR, IR, UV and MS spectral data of dengibsis and dengibsinin and a number of their pertinent derivatives.Aurantiamide acetate, dimethyl terephthalate and β-sitosterol have been isolated as the other constituents.
