Jintan Hitam atau Nigella sativa diketahui memiliki kemampuan sebagai antibakteri, seperti terhadap Staphylococcus aureus dan Escherichia coli. Kedua bakteri ini memiliki sifat yang berbeda namun memiliki kesamaan dari penyakit yang disebabkannya. Tujuan penelitian ini adalah untuk membandingkan efek antibakteri produk minyak jintan hitam (Nigella sativa) dalam bentuk kapsul antara bakteri Staphylococcus aureus dan Escherechia coli secara in vitro. Penelitian ini dilakukan pada bulan Januari 2012 - Desember 2012 di Laboratorium Mikrobiologi, Fakultas Kedokteran Universitas Andalas. Penelitian ini menunjukkan bahwa semua sampel jintan hitam yang digunakan tidak memiliki efek antibakteri terhadap Escherichia coli dan semua sampel tersebut memiliki efek antibakteri yang bervariasi pada Staphylococcus aureus. Analisis Anova menunjukkan bahwa masing-masing sampel minyak Nigella sativa memberikan efek berbeda secara signifikan pada pertumbuhan Staphylococcus aureus, bahkan enam diantaranya memiliki efek yang lebih baik daripada Cepoperazon (25 mm) sebagai kontrol yang digunakan.
