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, and performs high-temperature pressurization treatment in a solid state using discarded pericarp, and then ultrasonic treatment, and further treatment of enzymes to extract water and high-temperature pressurization alone. In comparison, a high content of punicalin or ellagic acid was obtained. In addition, since the pomegranate extract with an enhanced ellagic acid content extracted by the method of the present invention has an anti-stress or degenerative brain disease improvement effect, it can be used as a health functional food composition for preventing or ameliorating stress and degenerative brain diseases. .
