Abstract :Fruits of Japanese plum (Prunus salicina Lindl.) cultivar Angeleno were harvested from Egirdir, Isparta, between June and September 2023 at four intervals (H1-H4) to investigate pomological and biochemical changes during fruit development and ripening. Fruit width increased by approximately 67%, fruit length by 89% and fruit flesh diameter by 128% and the average fruit weight increased over 500% from June to September. Colorimetric variables showed that fruit color changed from green to red during fruit maturation. Total chlorophyll, carotenoid and protein content of fruits decreased at the commercial harvest stage (H4) compared to the pit hardening stage (H1). Total phenolic content increased, but flavonoid content did not change significantly. Though the antioxidant capacity of fruits changed between the ripening stages, both CUPRAC and DPPH values were similar at the H1 and H4 stages. However, total soluble and reducing sugar contents increased steadily throughout the fruit growth stages. The results showed that fruit development stages have different biochemical contents, and plum fruit could be a good source of polyphenols and antioxidants for the human diet.
