    This study was designed to maximize extract yields of functional components in Angelica gigas Nakai byextrusion process. In addition, the optimizing condition of the extrusion process was established to increase the extraction ofthe functional components in A. gigas. The total polyphenol was increased by 40% compared to a control. And the optimizingcondition was that the screw speed was 62.76 rpm, the amount of A. gigas powder was 34.79 ㎏/h, and the amount ofwater was 4.44 ㎏/h. The result of antioxidant activities of A. gigas extrusion, the inhibition of oxidization had the effect of10.29 ~ 14.59% compared to a control. The content of decursin and decursinol angelate, which were index components, was6.37%; it was increased by 16.64% compared to a control (5.31%) and showed a significantly difference (p < 0.05). And theoptimizing condition was the screw speed 93.71 rpm, the amount of A. gigas powder was 28.67 ㎏/h, and the amount ofwater was 9.9 ㎏/h.
