COMPARATIVE ACCOUNT ON GC-MS ANALYSIS OF MENTHA ARVENSIS L. CORN MINT FROM THREE DIFFERENT LOCATIONS OF NORTH INDIA

The essential oil analysis of Mentha arvensis L. (Corn Mint) has been done for the first time from three locations of NorthIndia. The extraction yields for the essential oils of three locations of M. arvensis were: 0.38% for sample M-1 collectedfrom Fatehpur (415m), 0.31% for sample M-2 from Dhameta (435m) and 0.36% for sample MP from Patiala (250m). Theoils were analyzed by GC-MS, the components of oil were identified by comparing their retention indices and mass spectrafragmentation patterns with those stored on the MS-computer library and also from the published literatures. The majorconstituents reported from essential oils of M. arvensis were: L-Menthone, Menthol, Isomenthone, Eucalyptol, Piperitoneoxide, Carvone, dl-Limonene, trans-Dihydrocarvone, Germacrene-D, etc. from all three samples collected from Punjab andHimachal Pradesh of Northern India.
