This study provides a comprehensive characterization of Physalis peruviana L., covering the nutritional composition of the fruit and the phytochemical profiles and in vitro bioactive properties of berry and calyx extracts. The fresh fruit stood out as a source of dietary fiber (5.16 g/100 g) and is low in fat (0.49 g/100 g). A 100-g serving also contained notable amounts of ascorbic acid (32.0 mg), tocopherols (2.34 mg), potassium (253 mg), phosphorus (45 mg), and magnesium (20 mg). HPLC-DAD-ESI/MS analysis tentatively identified five physalin derivatives and one withanolide in the fruit extract, which showed significant antiproliferative activity against human colorectal adenocarcinoma (Caco-2) and non-small-cell lung carcinoma (NCI-H460) cells. The calyx extracts contained three phenolic acids and four flavonoids, demonstrating high antioxidant activity through physiologically relevant cell-based assays, the ability to inhibit advanced glycation end products (AGEs) formation and nitric oxide production, and also antiproliferative properties. These findings highlight goldenberry as a nutrient-dense fruit rich in vitamins and functional compounds with potential health benefits, supporting its recognition as a “superfruit”. Furthermore, the fruit calyx emerged as a valuable source of bioactive secondary metabolites with potential applications in food and pharmaceutical industries and related sectors.
