Abstract:
The antimicrobial activity from flower, leaf, and seed of Hibiscus tiliaceus was screened
on Escherichia coli, Pseudomonas aentginosa, Bacillus subtilis and Staphylococcus
aureus. Methanol, hexane, ethyl acetate and water were used as extractive solvent. The
antimicrobial effect of the extract was tested using Disc diffusion method with
concentration of 20 mg/ml for each extracts. Based on the result, it reveals that most of
the extracts only gave positive result on Bacillus subtilis and Pseudomonas aeruginosa.
All of the extracts were do not effective on Escherichia coli and Staphylococcus aureus
as it only exhibited trace and no inhibition zone at all.
