We investigated the amount of polyphenols present in three types of stone fruits (peaches, plums, and prunes) that were produced in Japan during 2018 and 2019 using reversed-phase high-performance liquid chromatography (HPLC) with photodiode arrays and by normal-phase HPLC with fluorescence-based detection. Principal component analysis revealed the characteristics of the three fruit types: the major contributors of polyphenolic content in peaches were catechin, procyanidin B1, and 5-caffeoylquinic acid; those in plums, procyanidin B4, epicatechin, and procyanidin B5; and those in prunes, 3-caffeoylquinic acid and peonidine-3-rutinoside. Next, their antioxidative activity was assessed using hydrophilic oxygen radical absorbance capacity (H-ORAC). The sum of all polyphenol contents was significantly correlated with H-ORAC values (R2 = 0.6205). Both the concentrations of flavan-3-ols and procyanidins measured by reversed- and normal-phase HPLC were significantly correlated with H-ORAC values (R2 = 0.7248 and 0.7036, respectively). This work provides a reference for further investigations of stone fruit functions.
