Chemical analysis and Identification of the components of two ecotypes of(MenthaLongifolia L. (in Iran province

ABSTRACT: Menthais common named (MenthaLongifolia L. (belongs to Lamiaceae family. Grows aswild in various regions of Iran. The aerial parts of plant collected from two provinces of Iran were analyzed by using GC/MS. The 37 and 33 compounds were identified in dried aerial parts Isfahan and Lorstan province,respectively.The major components in Karkas mountain, Isfahan provincewere; 1,8-Cineole (15.58%), Piperitenone oxide (15.05%), Pulegone (9.58%) and Sabinen (9.52%). The major components in Gahar, Lorstan province were;p-Mentha-3,8-diene (10.531%), 2,6-Dimethyl-2,4,6-oc tatriene (10.132%), Sabinene (6.98%), B-Caryophyllene (6.971%), Piperitone oxide (6.77%) and Pulegone (6.60%). In conclusion, ecotypes collected from Isfahan province showed higher amounts of the components than Lorestan. Therefore, selection from ecotypes belong to Isfahan province have higher genetic gain than Lorestan ecotype.
