<jats:title>Abstract</jats:title><jats:p>By chromatographic examination of the extracts of various tissues of the Victoria plum <jats:italic>(Prunus domestica</jats:italic> var. Victoria), little difference was noted in the samples collected at different times of the year. Scopoletin, (+)‐catechin, (‐)‐<jats:italic>epi</jats:italic>catechin, rutin and chlorogenic acid have been identified in the extracts. The strong blue fluorescence of the pathological heartwood under ultra‐violet light was attributed to scopoletin. A pronounced difference exists between the phenolic constituents of the woody tissues of Victoria plum and those of the Asian <jats:italic>Prunus</jats:italic> spp.
