ABSTRACT:

Chemically  modified  and  unmodified  oil  of  Ageratum  conyzoides  were  compared  for  improved  activity  against some  selected  strains  of  pathogenic  microbes.  The  oil  from  fresh  flowers  of  the  plant  was  extracted  by  steam distillation.  A  portion  of  the  extracted  oil  was  modified  by  rapid  bromination  and  its  activity  against Staphylococcus  aureus,  Klebsiella  aerogenes,  Streptococcus  spp,  Escherichia  coli,  Bacillus  anthracis,  Candida parapsilosis,  Candida  albicans  and  Trichophyton  mentagrophytes  were  compared  against  those  of  the  pure  oil. The  results  obtained  showed  that  the  chemically  modified  oil  of  A.  conizoides  exhibited  increased  antifungal properties  than  the  pure  oil.  C.  parapsilosis  and  K.  aerogenes  were  totally  resistant  to  the  modified  oil.  T. mentagrophytes  and  S.  aureus  which  are  pathogenic  skin  microbes  were  totally  resistant  to  the  pure  oil  but  were sensitive  to  the  chemically  modified  oil  making  this  type  of  oil  a  good  active  ingredient  in  ointments  against  the microbes.
