摘要：Peppermint (Mentha piperita L.) is cultivated all over the world for its use in flavor, fragrance, medicinal, and pharmaceutical applications. Pot experiments were carried out to study the effect of different levels of humic acid, application of foliar nutrition and their interactions on the essential oil extracted from peppermint herb. Essential oil con tent (% or ml plant -1 ) increased at all humic acid, foliar nutrition and humic acid with foliar nutrition levels. The highest accumulation o f essential oil content (0.25 % or 0.19 ml plant -1 ) was recorded at the highest humic acid level (0.4 g L -1 ) with 10 g L -1 of foliar nutrition interaction. It is clear that the highest amounts of major co nstituents were produced under the treatments of 0.4 g L -1 of humic acid with 7.5 g L -1 of foliar nutrition (for menthol), 0 g L -1 of humic acid with 5 g L -1 of foliar nutrition (for menthone), 0.4 g L -1 of humic acid with 0 g L -1 of foliar nutrition (for isomenthone) and 0.2 g L -1 of humic acid with 0 g L -1 of foliar nutrition (1, 8- cineole). It is evident that the concentration of monoterpene hydrocarbonsas highest in the essential oil of plants grown under 0.2 g L -1 of humic acid with 10 g L -1 of foliar nutrition. The highest values of oxygenated monoterpene resulted from the treatments of 0.4 g L -1 of humic acid with 0 g L -1 foliar nutrition.
