The aim of this study was to investigate the antioxidant activities of various parts (barks, buds, and leaves) of <em>Cinnamomum cassia </em>extracted with ethanol and supercritical fluid extraction (SFE). For the antioxidant activity comparison, IC<sub>50</sub> values of<sub> </sub>the SFE and ethanol extracts in the DPPH scavenging assay were 0.562–10.090 mg/mL and 0.072–0.208 mg/mL, and the Trolox equivalent antioxidant capacity (TEAC) values were 6.789–58.335 mmole Trolox/g and 133.039–335.779 mmole Trolox/g, respectively. In addition, the total flavonoid contents were 0.031–1.916 g/ 100 g dry weight of materials (DW) and 2.030–3.348 g/ 100 g DW, and the total phenolic contents were 0.151–2.018 g/ 100 g DW and 6.313–9.534 g/ 100 g DW in the SFE and ethanol extracts, respectively. Based on the results, the ethanol extracts of <em>Cinnamon</em> barks have potential value as an antioxidant substitute and this study also provide a better technique to extract the natural antioxidant substances from <em>C. cassia</em>.
