Popis: The structure of gentiogenal, (+/-)5-formyl-6-methyl-3,4-dihydro-1H,6H-pyrano-[3,4-c-]-pyran-1-one, a conversion product of the aglucone of gentiopicrin (gentiopicroside), isolated from BLACKSTONIA PERFOLIATA (Gentianaceae), was elucidated by (1)H- and (13)C NMR spectroscopic, mass spectrometric and X-ray diffraction methods. In a TLC bioassay gentiogenal showed fungitoxicity towards PENICILLIUM EXPANSUM.
