title: Composition of volatile compounds and in vitro antimicrobial activity of nineMenthaspp.
abstract: BACKGROUND
  Menthaplants containing over 25 species are aromatic perennial herbs. These species have been interested and widely used because of various clinical findings. Many volatile compounds facilitate environmental interactions such as protecting themselves from pathogens, parasites, and herbivores. Therefore, this study assessed comparison of volatile composition and antimicrobial activity from nineMenthaspecies. The composition of volatiles was investigated from the aerial parts of nine differentMenthaspecies using gas chromatography-mass spectrometry (GC/MS). In addition, screened antimicrobial activities against six food borne pathogenic bacteria using extracts obtained these plants.
  
  
  RESULTS
  77 volatile compounds were identified in total and it included 13 monoterpenoids, 19 sesquiterpenoids, and others. In particular, monoterpenoids such as eucalyptol (9.35-62.16 %), (±)camphorquinone (1.50-51.61 %), and menthol (0.83-36.91 %) were mostly detected as major constituents inMenthaspecies. The ethanol extract of nineMenthaspecies showed higher activity compared to other solvent extracts (methanol, hexane, di ethyl ether). Among these nineMenthaspecies chocomint showed higher inhibition activity against all bacteria.
  
  
  CONCLUSIONS
  It is concluded that monoterpenoids are mainly rich inMenthaplants. Moreover, most of extracts obtained fromMenthashowed strong antimicrobial activity against bacteria. Of these, chocomint indicates the highest inhibition activity.
