Abstract

The current study was conducted to investigate antibacterial activity of Alseodaphne andersonii. (King ex Hook. f.) Kosterm. (Lauraceae) leaf extracts against 15 strains of pathogenic bacteria. Inhibition of bacterial growth was investigated using disk diffusion methods. Methanol leaf extract of Alseodaphne andersonii. was active against all assayed bacteria. The minimal inhibitory concentration (MIC) values and minimal bactericidal concentration (MBC) values were also determined. Results indicated that Alseodaphne andersonii. extracts must possess major antibacterial components against infectious microorganisms. The MIC and MBC of methanol extract of leaves against Staphylococcus aureus. were found to be 0.414 and 6.62 mg/mL, and for Staphylococcus epidermidis. 0.207 and 3.31 mg/mL, respectively. Alseodaphne andersonii. might provide promising therapeutic agents against infections with bacterial organisms. This is the first report about the antimicrobial activity of Alseodaphne andersonii.. The plant is reported to be used as timber only.
