A new flavone, 5,2',5'-trihydroxyflavone and 2',β-dihydroxychalcone (β-diketone) were isolated from the farinose exudate of Primula pulverulenta.These structures were established on the basis of spectral data and confirmed by total synthesis.A transformation experiment suggest that the β-diketone is converted into flavone during isolation procedures. - Keywords: Primula pulverulenta; Primulaceae; farinose exudate; 5,2',5'-trihydroxyflavone; 2',β-dihydroxychalcone; conversion of β-diketone into flavone.
