Aim: The dietary intake of medicinal food with antioxidant activity and required amounts of trace elements is important to pursue good healthy life. In our study, we aimed to determine the antioxidant capacity and metal content of goldenberry (Physalis peruviana L.) fruit sold in markets in Kayseri. Material and Method: The antioxidant capacity of P. peruviana fruit was determined by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging assay. The DPPH radical scavenger capacity of the methanol extract of fruit was compared with known antioxidants such as ascorbic acid, gallic acid, and butylated hydroxytoluene (BHT) as references. The metal content of P. peruviana fruit was measured by using atomic absorption spectrometer (AAS). Results: The fruit of P. peruviana was found to possess DPPH free radical scavenging activity but the antioxidant capacity was lower than the standard substances. Inhibitory concentration 50% (IC50) values of P. peruviana, ascorbic acid, gallic acid, and BHT were determined as 32 mg/ml, 3.8 mg/ml, 3.51 mg/ml, and 1.21 mg/ml, respectively. As a result of the analysis by AAS, it was observed that P. peruviana fruit contented plentiful trace elements and the content of heavy metal was small amount or not detected. Discussion: These observations suggest that the fruit of P. peruviana has a potential source of antioxidant and trace elements of natural origin.
