초록

The aim of this research was to investigate the antibacterial activity of Clerodendron trichotomum. Antibacterial activities of the n-hexane, methylene chloride (MC), ethyl acetate,and n-butanol fractions from C. trichotomum were tested against Staphylococcus aureus, Escherichia coli, and Helicobacter pylori. The n-hexane and MC fractions showed antibacterial activity against H. pylori at a concentration of 1.7 mg/mL and showed inhibition zones of 10 and 11 mm in disc assay, respectively. Further testing of 22-dehydroclerosterol and β-amyrin (each 3.4mg/mL) from the MC fraction of C. trichotomum revealed moderate antibacterial effects against E. coli, S. aureus, and H. pylori. In particular, β-amyrin showed clear zones of 12 and 13mm against E. coli and H. pylori, respectively, suggesting its potential as an antibacterial agent. The active compounds from C. trichotomum might provide a promising therapeutic agent against infections by E. coli, S. aureus, and H. pylori.
