Antimicrobial activities in root extracts of Limonium spp. growing in Afyonkarahisar, Turkey.

The study was conducted to evaluate the antimicrobial properties of the root extracts of some Limonium species, viz. L. effusum, L. globuliferum and L. lilacinum. The root extracts obtained were evaluated against 9 bacteria, and 12 fungi isolated from hazelnut, and walnut. The maximum antibacterial activity was obseved to be in methanol extract. Furthermore, the ethanol extract of L. lilacinum also had the maximum antibacterial activity against L. monocytopenus. The methanol extract of L. lilacinum exhibited the most potent antibacterial activity among the tested extracts. Our findings showed that Limonium root extracts significantly reduced the growth of fungi as compared to control. The inhibitory effects of the Limonium root extracts on the mycelial growth of 12 fungal species isolated from nuts in agar diffusion plate assay showed fungal growth reduced at the 6th day of experiment. The mycelial growth of A. alternata was maximum inhibited (100%) by L. globuliferum water extracts on 6th day.
