摘要

The present invention relates to a method for efficiently extracting punicalin or ellagic acid from pomegranate. The present invention selects varieties with excellent content of punicalin and ellagic acid, treats them by high-temperature pressure treatment in a solid state using discarded skin, and then ultrasonically treats the enzymes, thereby extracting water and treating the high temperature pressure alone. Compared, a high content of punicalin or ellagic acid was obtained. In addition, the pomegranate extract with enhanced ellagic acid content extracted by the method of the present invention has an effect of improving anti-stress or degenerative brain disease, and thus can be used as a health functional food composition for preventing or improving stress and degenerative brain disease. .
