In general, stepwise hot steaming process is known to be effective in improving its biological activities; however, not much employed in processing Codonopsis lanceolata due to its hardness. In this study, C. lanceolata was first pretreated with warm water at 50˚C and 60˚C for two hours, then steamed for 3 hours. Antioxidant activities of 70% ethanol extracts were compared with the extract from the water solven: 41.58% vs 8.98% of DPPH radical scavenging activity in adding 1.25 mg/m㎕ of steamed extract and water extract, respectively. Reducing power of steamed and fresh C. lanceolata were also measured as 1.39 and 0.71. Total poly phenolic of the steamed extract was estimated as 12.11 mg/g, compared to 3.98 mg/g fresh C. lanceolata. Total flavonoid contents were also obtained as 11.48 mg/g, compared to 7.11 mg/g of fresh C. lanceolata. In comparing phenolic acids profiles in the extract, in general higher amounts of gallic acid, trans-ferulic acid, vanillic acid were obtained possibly by easy release of active components during thermal processing, which results in better antioxidant activities than that of water extract. This findings can also be supported by result that the ethanol extract showed better activities than the water extract.
