Abstract

Staphylococcus aureus are examples of Grampositivebacteria that can cause infection.Treatment of infection with antibiotic synthesiscan bring its own problems, namely the resistanceof bacteria to antibiotics. Resistant bacteria is abacterial pathogen that is capable of formingbiofilms on living beings. Traditional medicine canbe another alternative in the treatment ofinfections. Natural compounds that have thepotential as an antibacterial commonly containsteroids, tannins, polyphenols, flavonoids1),alkaloids, saponins2).Some studies related to the use as an antibacterialBintaro explained that the mangrove plant thatbelongs to the family Apocynaceae is grown widelyin the southern coast of East Asia and the IndianOcean has antibacterial activity3).This study was conducted to determine theantibacterial activity and antibiofilm of ethanolicextract from Cerbera odollam flower againstStaphylococcus aureus.

Abstract

Biofilm is a structural form of a group ofmicroorganisms protected by matrik extracellularcalled Extracellular Polymeric Substance (EPS),where EPS is a product produced by thesemicroorganisms itself and as a shelter from thebad influence in environment. The structure ofthese matrix is strings which cross each otherwhich can be adhesive for biofilm4).Biofilm from Staphylococcus aureus seen inchronicle infection cases as ulcer on diabeticsfoot, venous statis ulcer and pressure sores.Patients with infection wound with chronicleulcer in vein feet found positive culture ofStaphylococcus aureus as much as 88-93,3% froma number of infection found.Figure 1. Cerberra odollam Gaertn.Bintaro can be used as an analgesic,anticonvulsant, kardiotonik and antihypertensive2).The aim of this study is to test the effectivenessof the ethanol extracts of bintaro leaves (Cerberraodollam Gaertn.) towards the Staphylococcusaureus formation by in vitro.MATERIALSBintaro leaves (Cerberra odollam Gaertn.),Staphylococcus aureus culture ATCC 6538, petridish, ose wire , micro pipet, autoclave (AllAmerican Model No 25x, USA), incubator(Memmert and Binder, Germany), Laminar AirFlow (LAF) (Type V-130, Indonesia), microplate,microplate reader (Thermofisher Scientific,America), vacuum rotary evaporator (BÜCHI,Germany), weight analytic (Sartorius TE 214 S,Germany), oven (Memmert, Germany).

Abstract

The purpose of this study was to determine the concentration of papaya (Carica papaya L.) leaf extract which gave antibacterial activity and to determine the effect of increasing concentrations of papaya (Carica papaya L) leaf extract on physical quality, effectiveness of antibacterial inhibition and stability in the gel form. The antibacterial activity was tested using the well method. The evaluations consist of physical quality tests including organoleptic, pH, homogeneity, dispersion and viscosity; effectiveness (antibacterial activity); safety; acceptability and stability (organoleptic, pH and viscosity). The results showed that the higher the concentration of extract of papaya leaf, the higher the antibacterial activity and also influenced its physical quality and the stability. The concentration of papaya leaf extract (Carica papaya L) which have the highest antibacterial activity is 30%. The increasing of the concentration of papaya leaf extract (Carica papaya L.) affected the physical quality (pH, viscosity and dispersion), the effectiveness (antibacterial activity) and stability (pH stability and viscosity stability). The best formula in this study is formula 2 (papaya leaf extract 20%) which fulfill requirements of physical (organoleptic), pH, viscosity, dispersion, homogeneity, have antibacterial activity, safety and stability test
