Abstract

ABSTRAK             Penyakit infeksi yang disebabkan oleh bakteri Escherichia coli dan Staphylococcus aureus dapat ditangani dengan antibiotik. Terong belanda merupakan tanaman yang kaya nutrisi serta bermanfaat menghambat pertumbuhan bakteri. Penelitian ini bertujuan untuk mengetahui aktivitas antibakteri ekstrak glikosida buah terong belanda terhadap bakteri Escherichia coli dan Staphylococcus aureus serta mengidentifikasi senyawa aktifnya. Ekstraksi dilakukan dengan maserasi, pemisahan dan pemurnian dengan KLT, pengujian aktivitas antibakteri dilakukan dengan metode sumur difusi, dan identifikasi senyawa aktif menggunakan spektrofotometri UV-Vis dan FTIR.
