Summary: | Introduction : Staphylococcus aureus is one of the normal flora in human skin,
mucous membrane, oropharynx, gastrointestinal tract, and vagina which potentially
becomes a pathogen. The excessive growth of S. aureus can cause many serious
infection whether in human or animal. And nowadays, some of S.aureus have become
resistant to antibiotic caused by its mutation. According to that case, researcher try to
find an alternative solution by using Aloe vera gel ethanol extract that some other
researchers say it contains antraquinone, tannin, polysaccharide, flavonoid, and
saponin as anti bacterial compound. This research aimed to find out the effectiveness
of Aloe vera gel ethanol extract in inhibiting Staphylococcus aureus.
Methods : This research is designed as an laboratorium experimental with difusion
and dilusion method. Test performed with using 100%, 75%, 50%, 25%, and 0%
concentration in difusion method and using 100%, 50%, 25%, 12,5%, 6,25%,
3,125%, 1,5625% concentration , positive control (+) and negative control (-) in
dilution method.
Results : There is no inhibition zone in difusion method, also no minimum inhibitory
concentration and no bactericidal concentration can be seen in dilution method that
inhibit the growth of Staphylococcus aureus. This result might be related to the
minimal amount of active compound in this sample, that is taken from Aloe vera gel.
The amount of active compound can be influenced by the environment, difference in
Aloe’s age, degradation process and enzymatic reaction, difference in extraction
method and also influenced by oxidation process when it’s exposed to air.
Conclusion : Based on the results, anti bacterial activity of Aloe vera gel ethanol
extract towards Staphylococcus aureus can not be determined in difusion and dilution
method. |
