| Abstract | This study aimed to determine the antioxidant activity of papaya (Carica papaya L.) stem and leaf extracts using the DPPH method and to compare their activity with vitamin C as a positive control. The study was conducted experimentally through sample preparation, drying-loss characterization, extraction using 70% ethanol, phytochemical screening, and antioxidant activity testing using the DPPH method with a UV-Vis spectrophotometer. Antioxidant activity was expressed as percentage inhibition and IC30 values. The results showed that vitamin C had an IC50 value of 8.7515 ppm, papaya leaf extract had an ICso value of 173.8008 ppm, and papaya stem extract had an IC50 value of 301.8982 ppm. Based on the IC50 values, vitamin C showed the strongest antioxidant activity, followed by papaya leaf extract and papaya stem extract. Thus, under the conditions of this study, papaya leaf extract showed stronger antioxidant activity than papaya stem extract. | 1 |
