Abstract
Patikala leaves are widely used by the community as a medicine for skin
diseases and antimicrobials in food. The purpose of this study was to determine
the antibacterial activity of patikala leaf extract from various types of
solvents based on the level of polarity and the class of compounds that act as
antibacterials. The extraction method used is maceration using several
solvents, namely n-hexane, ethyl acetate, and ethanol. Then screened the
compound class and tested its antibacterial activity using the diffusion
method. The results of the research are ethanol, ethyl acetate and n-hexane
extracts from patikala leaves can inhibit bacterial growth S aureuswith
diameters of inhibition zones namely 8.91 mm ethyl acetate, 8.17 mm ethanol and
8.03 mm n-hexane. on bacteria E. colithe ethanol and ethyl acetate
extracts had an inhibition of 8.75 mm and 7.59 mm, while the n-hexane extract
had no antibacterial inhibition, so the antibacterial activity of the patikala
leaf extract was smaller when compared to the (+) tetracycline control. So it
can be concluded that n-hexane extract, ethyl acetate extract and ethanol
extract have activity against bacteria Staphylococcus aureus whereas in
bacteria Escherichia coli only ethanol and ethyl acetate extracts that
have an antibacterial effect.).
