<p><em>Curculigo orchioides</em> Gaertn. is used in traditional medicine in Vietnam. The antioxidant potential of <em>Curculigo orchioides</em> was<em> </em>evaluated through DPPH radical scavenging and total antioxidant capacity method. The data resulted from DPPH radical<em> </em>scavenging activities indicated that <em>Curculigo orchioides</em> displayed the good activities with low IC₅₀value (22.78μg/mL), approximately 1.5 times less than that of curcumin (34.34 μg/mL). The total antioxidant capacity of the extract of <em>Curculigo orchioides</em> contained 132.48 ± 1.48  mg GA/g or  264.45 ± 2.34 μmol AS/g. Content of compounds from Curculigo orchioides including the total phenolic, total flavonoid, polysaccharides, and saponin - triterpenoids were examined using the colorimetric method with reagents. The content of phenolic compounds, flavonoid compounds, polysaccharides, and saponin – triterpenoids found in <em>Curculigo orchioides</em> was  196.24 ± 1.45 mg GAE/g, 78.49 ± 1.78  mg QUE/g, 4.34 ± 0.08 %, 47.60 ± 0.24 mg Rb1/g (Rb1: (Gypenoside III)), respectively. Specifically, the total saponin - triterpenoid content of <em>Curculigo orchioides</em> has been reported for the first time.</p>
