The objectives of this study were to compare the antioxidant activities by high pressure extraction of Codonopsis lanceolata from different cultivation areas; Hoeng-sung, Jeju island, and China. Total phenolic acid contents of Hoeng-sung, Jeju, China were estimated as 732.11, 640.25, and 584.85 mg QUR/100 g DW, respectively. The flavonoids contents of Hoeng-sung, Jeju, China were measured as 80.37, 76.46, and 74.55 mg QUR/100g DW, respectively. Generally, contents of phenolic acid and flavonoids, HPE was higher than conventional extraction process. Hoeng-sung Codonopsis lanceolata showed 64.33% of DPPH radical scavenging activity (EDA, %) in 3.2 mg/ml of Hoeng-sung Codonopsis lanceolata. The reducing power of Hoeng-sung cultivation area Codonopsis lanceolata also showed the high activity as 3.15. In generally, antioxidant activities of Codonopsis lanceolata were increased by high pressure extraction process. Based on these results, higher contents of flavonoids and total polyphenols were found extracted by high pressure extraction of Codonopsis lanceolata grow in Hoeng-sung area than others.
