Abstract

The aim of this study is to investigate the antioxidant activities of various parts (barks, buds, and leaves) of Cinnamomum cassia extracted with ethanol and supercritical fl uid extraction (SFE). For the antioxidant activity comparison, the SFE and ethanol extracts in DPPH scavenging eff ects of IC50 were 0.562-10.090 mg/mL and 0.072-0.208 mg/mL, and the trolox equivalent antioxidant capacity (TEAC) were 6.789-58.335 mmole trolox/g and 133.039-335.779 mmole trolox/g, respectively. In addition, the total fl avonoid 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 Cinnamon barks have the potential valuable as an antioxidant substitute and this study also provide a better technique to extract the natural antioxidant substances from C. cassia.
