하나의 과일, 두 가지 기능: 추후이 자두 껍질과 과육의 뚜렷한 항산화 및 생리활성 분석

This study aimed to compare the antioxidant and bioactive properties of peel and flesh extracts from Prunus salicina Lindl. var. salicina ‘Chuhui’ (hereafter referred to as Chuhui plum) and to evaluate their potential as high-value natural functional materials. Korean markets in early September 2024, and all experiments were conducted between mid-September and October. Analysis of DPPH and ABTS radical scavenging activity revealed that the peel extract consistently showed significantly higher antioxidant activity than the flesh extract across all tested concentrations. In addition, the total polyphenol content in the peel was approximately 3.2 times higher than that in the flesh. Unlike previous studies that focused on single whole-fruit extracts, this research conducted a quantitative comparison by plant part and demonstrated the functional potential of Chuhui plum peel through bioactivity evaluation. Notably, the peel (often discarded as a by-product of fruit processing) was shown to meet the criteria of sustainability and resource circulation, suggesting its potential as a high-value functional material in natural antioxidant development, food biotechnology, and plant-derived skincare applications.
