The aims of this study were to optimize the supercritical carbon dioxide extraction conditions on the extraction yield and hydrolyzable tannins content of Quercus infectoria (QI) galls and determine the bioactivities of the gall extracts related to wound healing. Experimentally, the QI gall was extracted using the supercritical carbon dioxide (SC‐CO 2 ) extraction method at different operating conditions which were pressure (20 to 30 MPa), temperature (50 to 70°C), and mean particle size (0.50 to 1.50 mm). The optimum values of pressure, temperature and mean particle size to achieve optimum responses (galls extraction yield: 6.02%, tannic acid concentration: 6,149.71 mg/g sample; gallic acid concentration: 96.85 mg/g sample) were 28.11 MPa, 50.43°C, and 1.25 mm, respectively. The findings also demonstrated that the extracts possess antioxidant activity and cell proliferation and migration abilities.
