The most efficient isolate was AF3 identified as &lt;em&gt;Aspergillus tubenginses&lt;/em&gt; ASH4 by 18S rRNA gene sequencing. Anofinic acid is an isolated active metabolite biosynthesized by A. tubenginsis was extracted from ethyl acetate with UPAC name of 2,2-dimethyl-2H-1-benzopyran-6-carboxylic acid. It shows a strong antimicrobial activity against human pathogenic bacteria such as &lt;em&gt;Pseudomonas aeruginosa, Staphylococcus aureus, Escherichia coli, Candida albicans&lt;/em&gt; and&lt;em&gt; Bacillus subtilis&lt;/em&gt;. Moreover, anofinic acid inhibits biofilm formation and has antioxidant activity, with strong activity against some carcinoma cells such as HCT-116, Hep-G2 and MCF-7. &lt;strong&gt;Conclusion:&lt;/strong&gt; Anofinic acid was purified from the endophytic &lt;em&gt;Aspergillus tubenginses&lt;/em&gt; crude extract and showed antimicrobial, antibiofilm, antioxidant, anticancer activities.&lt;/p&gt;
