Cornus fructus has been used as a tonic, astringent, and haemostatic agent in Korea, China, and Japan. In this study, the fruit of Cornus officinalis was treated with different osmotic pressures, pH values, heat, and ethanol percentages in order to establish optimum extraction conditions for gallic acid, an example of a hydrolyzable tannin. The extract was analyzed by HPLC and LC-MS/MS to identify the gallic acid. As a result, the highest extraction rate of gallic acid (1.57 mg/g) occurred when the Cornus fructus was extracted with 100% ethanol for 1 hr at 80oC. Also, when it was treated with 70% ethanol for 24 and 48 hr, contents of gallic acid were 1.35 and 1.50 mg/g, respectively.
