โœฆ Synopsis


The volatile constituents of the essential oils of dierent parts (shoot stem, shoot leaf, stolon stem, stolon leaf) of cornmint, Mentha arvensis L., grown under semi-arid tropical climatic conditions were investigated. The shoot leaf gave the highest yield of oil (0.62%), while the stems produced negligible quantities of oil (0.02%). Menthol was the major component of all the oils, with the highest percentage in shoot stem oil (78.16%) and the lowest in stolon (runner) stem oil (43.7%). b-Caryophyllene oxide was present in shoot (stem and leaf) oils, while a-phellandrene and terpinolene were identiยฎed in stolon (stem and leaf) oils, which were also richer in limonene, menthone and pulegone than the shoot oils. Signiยฎcant variations were observed among these oils for other components also. The underground rhizomes of cornmint plants did not yield any essential oil.
