    • Abstract

       

      The stem bark of Prunus puddum yields sakuranetin (Ia), sakuranin (Ib), genkwanin (II) and prunetin (III). The identification of sakuranetin is confirmed by the preparation of its diacetate and conversion to genkwanin. Prunusetin is shown to be only a slightly impure sample of prunetin. Though the components belong to different groups of anthoxanthins, they have the common feature that they are all 7-methyl ethers of 5∶ 7∶ 4′-trihydroxy compounds.
