%X <p>This study evaluated the antioxidant， antimicrobial， UV radiation resistance properties， and secondary metabolite content of fermented extracts from 20 endophytic fungi of diverse plant origins to assess their potential in cosmetic applications. ABTS and DPPH radical scavenging rates of fermentation broths and mycelial extracts were measured using microplate reader colorimetry， while ferric ion reduction capacity was determined via FRAP assay. Antimicrobial activity was assessed using the Oxford cup method. The results indicated strong antioxidant activity in fermentation broths of strains XY1， YZ6， ZJ29， XG4-2， and ZBS49. ZJ29 exhibited the highest DPPH radical scavenging rate （93.62%）， while XY1 showed the highest ABTS radical scavenging rate （90.47%）. ZJ29 fermentation broth also demonstrated an ABTS radical scavenging rate &gt;50% and the highest FRAP value （2 974.55 μmol<strong>?</strong>L<sup>-</sup>1）. Tyrosinase inhibition by ZJ29 and ZL18-1 mycelial extracts reached 60.62% and 98.10%， respectively， with ZJ29 fermentation broth showing the strongest inhibition（69.78%）. ZJ29 fermentation broth exhibited the highest inhibition against <i>Staphylococcus aureus</i>. The UVA and UVB absorbance of YZ6 and ZJ29 was higher than 2.8， and the UVA absorbance of YZ6 and ZJ29 was higher than 2.0 and 1.5， respectively. YZ6 mycelial extract also showed strong resistance to UVB and UVA， with absorbance of 1.5-2.5. YH3 and XY1 mycelial extracts contained the higher polyphenol （18.47 and 15.36 mg<strong>?</strong>g<sup>-</sup>1） and flavonoid （4.35 and 7.15 mg<strong>?</strong>g<sup>-</sup>1） content， respectively. ZL23 and ZJ29 had the higher triterpene content （16.79 and 11.20 mg<strong>?</strong>g<sup>-</sup>1， respectively）. In conclusion， ZJ29 mycelial extracts had superior antimicrobial， UV radiation resistance， and antioxidant activities， followed by YZ6 and XY1， highlighting their significant potential for daily chemical products.</p>
