Biochemical Characterization and Antioxidant Properties of Wild Plum (Prunus spp.)

Abstract

This study aimed to comprehensively evaluate the biochemical composition, antioxidant activity, and relationships among bioactive compounds in wild plum (Prunus spp.) fruit. Within the scope of the analyses, total phenolic content, total flavonoid content, and DPPH antioxidant activity were measured, and phenolic and organic acid profiles were determined. Descriptive statistics revealed that most compounds exhibited low variability, whereas some organic acids showed higher variability. Relationships among biochemical parameters were examined using correlation analysis, indicating that phenolic and flavonoid compounds made a significant contribution to antioxidant activity. Principal component analysis identified components explaining a large proportion of the total variance, with phenolic and flavonoid contents representing one component and organic acids representing another. The findings demonstrate that the biochemical profile of wild plum fruit can be reliably evaluated through detailed statistical analyses, providing a solid basis for quality assessment and biochemical characterization.
