Buah mengkudu (Morinda citrifolia, L.) telah digunakan sebagai obat herbal yang berfungsi sebagai analgesik, anti rdang dan antibakteri. Hal ini menunjukkan bahwa buah mengkudu mengandung senyawa aktif flavonoid, fenolik dan terpenoid Penelitian ini bertujuan menganalisis fenolik total buah mengkudu (Morinda Citrifolia, L) menggunakan pengekstrak etanol dan etil asetat serta uji hambat aktivitas terhadap bakteri Escherichia coli. Hasil analisis diperoleh fenolik total ekstrak etanol sebesar 171,91 mg/L dan ekstrak etil asetat 23,27 mg/L. Ekstrak etanol dan etil asetat dapat menghambat aktivitas bakteri Escherichia coli. Ekstrak etanol memiliki konsentrasi hambat minimum (KHM) sebesar 6,5% namun tidak demikian dengan ekstrak etil asetat, sehingga disimpulkan bahwa ekstrak etanol berpotensi menghambat aktivitas bakteri Escherichia coli lebih baik dibanding ekstrak etil asetat.
