ANTIBACTERIAL ACTIVITY OF ETHANOLIC EXTRACT AND INFUSE OF Bauhinia variegata LEAVES AGAINST Streptococcus pyogenes
Abstract: Bauhinia variegata
is a plant that has many virtues and widely grown in Indonesia. Yet the virtues
and uses are still limited as the shade and ornamental plant. The purpose of
this study is to determine the antibacterial ethanol extract activity and the
infuse of Bauhinia Variegata leaves toward Streptococcus pyogenes and to
determine the classes of compounds that have antibacterial activity. Bauhinia
variegata leaves are extracted by maceration and infundation with 96% ethanol
and distilled water. The test method of antibacterial activity is used disc
difusson Kirby Bauer methods. The Analyses of the compounds which are contained
in the Bauhinia Variegata leaves are done by TLC (Thin Layer Chromatography)
and test tubes. The results showed that ethanol extract and infuse of Bauhinia
Variegata leaves has no antibacterial activity toward Streptococcus pyogenes.
TLC results and test tubes showed that the ethanol extract of Bauhinia
Variegata leaves contain tannins, saponins, terpenoids, and alkaloids. While,
the infuse of Bauhinia variegata leaves are saponins and alkaloids.
