Abstract: Kelor (Moringa oleifera) merupakan tanaman tropis yang banyak ditemukan di Indonesia dan dikenal memiliki berbagai manfaat kesehatan. Daunnya mengandung senyawa metabolit sekunder seperti flavonoid, alkaloid, tanin, fenolat, serta senyawa aktif glukosinolat dan isothiocyanate yang berpotensi sebagai antibakteri. Daun kelor juga diketahui memiliki aktivitas farmakologi seperti antioksidan. Antioksidan dapat menghambat terjadinya stres oksidatif dalam tubuh dengan menjaga kestabilan radikal bebas. Senyawa β-karoten dan likopen dalam daun kelor berkontribusi terhadap aktivitas antioksidan tersebut. Salah satu bakteri patogen yang umum menginfeksi manusia adalah Helicobacter pylori, penyebab gangguan gastrointestinal serius seperti gastritis dan kanker lambung. Penggunaan antibiotik terhadap H. pylori memiliki keterbatasan akibat resistensi, sehingga alternatif berbasis bahan alam menjadi solusi potensial. Penelitian ini bertujuan mengeksplorasi potensi ekstrak daun kelor sebagai agen antibakteri terhadap H. pylori. Kandungan bioaktif dalam daun kelor berperan menghambat pertumbuhan bakteri melalui mekanisme antimikroba, sehingga dapat menjadi alternatif pengobatan yang lebih aman dan berkelanjutan. Moringa (Moringa oleifera) is a tropical plant commonly found in Indonesia and is known for its numerous health benefits. Its leaves contain secondary metabolites such as flavonoids, alkaloids, tannins, phenolics, and active compounds such as glucosinolates and isothiocyanates, which have antibacterial properties. Moringa leaves are also known to possess pharmacological activities such as antioxidants. Antioxidants can inhibit oxidative stress in the body by stabilizing free radicals. The β-carotene and lycopene compounds in Moringa leaves contribute to this antioxidant activity. One common pathogenic bacteria that infects humans is Helicobacter pylori, which causes serious gastrointestinal disorders such as gastritis and gastric cancer. The use of antibiotics against H. pylori is limited due to antibiotic resistance, making natural-based alternatives a potential solution. This study aims to explore the potential of Moringa leaf extract as an antibacterial agent against H. pylori. The bioactive compounds in Moringa leaves play a role in inhibiting bacterial growth through antimicrobial mechanisms, thus providing a safer and more sustainable alternative treatment.
