Studies on Antimicrobial of Impatiens balsamina extract (I) -Sereening of Antimicrobial on extract solvent-

To study antimicrobial activities of Impatiens balsamina, its leaf and stem was extracted by methanol and water. The extracts were tested their microbial inhibition activities against several microorganisms, staphylococcus aureus KCTC 1928, Escherichia coli KCTC 1116, Klebsiella pneumoniae KCTC 2690, Trichophyton mentagrophytes KCTC 6316. The methanol extract and water extract of the leaf and stem didn't show the inhibition effect on E. coli but showed the inhibition effect against the ohter 3 species of the microorganisms tested. The extract of leaf showed higher inhibition than the extract of stem. And the methanol extract showed higher inhibition than the water extract.
