Investigation of antimicrobial properties and chemical composition of different extracts of Sweet gum leaves (Liquidambar orientalis)

Different extracts of Liquidambar orientalisleaves were tested for their antimicrobial activity against eleven bacterial and one yeast strain by disc diffusion method. The was measured MIC. After that among the best detected.Volatile components ethanolic leaves sweetgum analysed GC/MS.Ethanolic showed inhibition zones Klebsiella pneumoniae (32mm). K.pneumoniae CCM 2318 lowest sensitivity to 0.008 mg/mL concentration extracts. Ethanolic L. orientalis var. MIC values ranging from 0.008-64 mg.mL-1 bacteria. GC/MS analyses allowed seven compounds be determined; benzenepropanol (%49.30) cinnamic acid (%35.89) main constituents extract. All varying degrees on microorganisms tested. due presence essential oils. Among most active compared reference antibiotics.
