Commonly, plant was cultivated by microgreen have potentially source of natural antioxidant agents. This study was conducted to utilize Cassia alata (C. alata) as a microgreen and evaluated the potential of Microgreen gelinggang as the source of natural antioxidant agents. The seed of Cassia alata was cultivated in Rockwool at room temperature (27±1oC). At the appearance of the first true leaves, about 21 days, microgreens were harvested from a triplicate of trays with sterilized scissors. The antioxidant activity assay using the DPPH (2,2-difenil-1-pikrilhidrazil) radical scavenging activity method. It was analyzed using spectrophotometry UV-VIS. The result showed that the IC50 values of Microgreen gelinggang were 1.789x103 ±0.0 µg/mL. It was a weak category antioxidant. This study indicated that the extract of Microgreen gelinggang has a potential source of natural antioxidant agents.
