Comparative study of antioxidant properties in three salak (Salacca zalacca) varieties from the Sleman region, Yogyakarta

This study investigates the phytochemical composition and antioxidant activity of three salak (Salacca zalacca) varieties cultivated in Sleman, Yogyakarta: Salak Manggala Klinting, Salak Madu, and Salak Pondoh Super. Total phenolic content (TPC), total flavonoid content (TFC), and evaluated antioxidant capacity through DPPH radical scavenging, ABTS and ferric-reducing antioxidant power (FRAP) assays were quantified using spectrophotometric analysis. The results revealed significant variation among the varieties, with Salak Pondoh Super exhibiting the highest level of TPC, as well as the strongest antioxidant activities (DPPH, ABTS, and FRAP). These findings suggest that varietal differences play a crucial role in the nutritional and functional properties of salak fruit. The study highlights the potential of local salak cultivars as natural sources of antioxidants, contributing to the development of functional foods and nutraceuticals derived from indigenous Indonesian fruits. © The Authors, published by EDP Sciences.
