The present invention provides a use of Anethum graveolens seed extracts for repairing brain nerve cell damage and slowing down neuronal apoptosis. Anethum graveolens seed extracts can effectively improve the gene expression levels of SOD1, SOD2 and GPx1, repair and retard the damage and apoptosis, and prevent and reduce the oxidative stress of brain nerve cells to reduce the brain damage of degeneration and weakness. The Anethum graveolens seed extracts is prepared by extracting Anethum graveolens seed using water, alcohols, or mixtures of water and alcohols as solvents.本發明提供一種萃取物用於修復腦神經細胞損傷及減緩腦神經細胞凋亡的用途，能有效提升腦神經細胞中SOD1基因、SOD2基因、與GPX1基因的表現量、有效修復與減緩腦神經細胞損傷及凋亡、以及能有效預防及降低腦神經細胞之氧化壓力，以達到減緩腦神經退化及衰弱之護腦功效。其中該蒔蘿籽萃取物，係蒔蘿籽以水、醇、或醇水混合物之溶劑所萃取而得。
