Dihydroflavonols from Prunus domestica

Abstract Seven compounds have been isolated from the heartwood of P. domestica . Two of them, 5,7,4′-trihydroxy-3-methoxyflavanone and 3,5,7-trihydroxy-6,4′-dimethoxyflavanone, are new natural products. The remaining five compounds were identified as isosakuranetin, prudomestin, dihydrokaempferide, naringenin and 3,5,7-trihydroxy-8,4′-dimethoxyflavanone. The last compound has been isolated for the first time from the genus Prunus .
