        This study was designed to evaluate antioxidant activity of Curcuma longa L. leaves treated by ultra highpressure extraction. Curcuma longa L. leaves was subjected to 5,000 bar for 5 and 15 min at 25℃ The highest phenolics andflavonoids content was observed in the treatment of high pressure extraction for 15 min (308.28㎍/㎎, 124.33㎍/㎎). TheDPPH scavenging activity was 82.34% at 1.0㎎/㎖ of Curcuma longa L. leaves treated by ultra high pressure process for 15min. The highest SOD-like acitivity of Curcuma longa L. leaves (1.0㎎/㎖) was observed at ultra high pressure extractionfor 15 min (67.54%). The high pressure extraction significantly increased the contents of phenolics and flavonoids and alsoenhanced the antioxidant activity. These results provide useful information for enhancing biological properties of Curcumalonga L. leaves.
