Abstract
The chemical composition of two North Indian (freshly distilled and a commercial oil samples) and four South Indian cornmint oils produced from different cultivars (‘Gomti,’ ‘MAS-1,’ ‘HY-77’ and ‘Shivalik’) were compared. All the oils contained menthol as their major constituent which varied from 70.4% in commercial North Indian oil to 87.2% in cultivar ‘MAS-1’ of South Indian origin. The North Indian oils contained minor quantities of camphene, (E)-β-ocimene, isopulegol and were richer in isomenthone, isomenthol + αterpineol and menthyl acetate compared to the South Indian oils. Among all the oils, one cultivar (‘MAS-1’) oil was unique with its high menthol content (87.2%).
