UJI AKTIVITAS ANTIBAKTERI FRAKSI ETIL ASETAT DAUN JAMBU BIJI (Psidium guajava L.) TERHADAP BAKTERI PENYABAB KARIES GIGI Streptococcus sanguis

Abstract: AbstrakJambu biji (Psidium guajava Linn.) adalah tanaman obat yang digunakan didaerah tropis dan subtropis untuk mengobati banyak gagguan kesehatan. Ekstrak daun jambu biji putih mengandung senyawa yang memiliki antibakteri. Namun dari fraksi daun jambu biji (Psidium guajava Linn.) saat ini belum diketahui khasiat antibakteri penyebab karies gigi yaitu Streptococcus sanguis. Uji aktivitas antibakteri dilakukan dengan difusi cakram (Kirby-bauer), dimana media Nutrient Broth  yang sudah dibiakkan dengan bakteri … Show more

“…, phenolic acids, and flavone glycosides and some of them have been shown to have antibacterial activity(Tanjung et al, 2022). Lemongrass extract has antibacterial activity because it contains flavonoids which can damage cell membranes and denature bacterial cell proteins so that they can inhibit bacterial growth(Atnawanty et al, 2020).The mechanism of action of flavonoids as antibacterial compounds is divided into 3, namely inhibiting nucleic acid synthesis, inhibiting cell membrane function and inhibiting energy metabolism. In inhibiting Purnama Fitri, Rasipin, Ari Suwondo | 268 the synthesis of nucleic acids, flavonoid compounds play an important role in the process of interaction or hydrogen bonding by accumulating nucleic acid bases thereby inhibiting the formation of DNA and RNA.…”
