  Objective: The objective of this study was to identify the total bioactive compounds, nutritional value and antioxidant activity in red dragon fruit powder. Methodology: Red dragon fruit powder was prepared using fresh red dragon fruit by sorting, bark stripping, cutting and pureeing the fruit into a slurry with a vacuum evaporator. Chemical analysis was performed using a spectrophotometer included total flavonoid, total phenolic acid and total anthocyanin. An approximate analysis was also performed. Results: The bioactive contents of red dragon fruit powder were: 210.02±0.83 mg/100 g total flavonoids, 386.09±1.52 mg/100 g total phenolic acid and 81.75±1.43 mg/100 g total anthocyanins. Red dragon fruit powder contained: 11.53% moisture, 4.17% ash, 5.30% crude fiber, 5.68% protein and 0.43% fat. Conclusion: Red dragon fruit powder contains highly bioactive compounds (antioxidants) and is a good functional food ingredient with the potential to scavenge 50% of free radicals using 1195.181 ppm red dragon fruit powder. This powder can also be stored for a long time.
