Objective:To evaluate the wound healing activity of the methanolic root extract of Buchanania lanzan Spreng.(B.lanzan),with a focus on antimicrobial and anti-biofilm properties.Methods:The extract was evaluated for its wound healing properties(excision and incision models)as evident from the analysis of tensile strength and wound contraction.The extract was also screened for antibacterial properties against different Cram positive and Gram negative bacterial strains.B.lanzan was also studied for its effect on biofilm formation and disruption of preformed biofilms.The synergistic effect of B.lanzan was determined in combination with gentamicin.Results:Topical application of B.lanzan(10%w/w ointment)significantly increased(40.84%)the tensile strength in the incision wound model.B.lanzan also showed significant wound healing activity in excision model and such significant activity was observed from the 9th day.Whereas Soframycin displayed significant wound healing activity from the 6th day.It was found that root extracts of B.lanzan revealed significant inhibition against all tested pathogens.B.lanzan displayed antimicrobial activity against Cram positive(MIC 0.625 mg/mL)and Cram negative(MIC0.625-1.25 mg/mL).B.lanzan was able to reduce biofilm formation and also caused disruption of preformed biofilms in a manner similar to ciprofloxacin.However,gentamicin was found to be ineffective against biofilms formed by Gram negative organism.According to the fractional inhibitory concentration index,B.lanzan displayed synergistic activity when it was combined with gentamicin.Conclusions:From this study it may be concluded that the root extract of B.lanzan revealed significant wound healing potential,which was supported and well correlated with pronounced antibacterial activity of the tested plant parts.
