ABSTRACT

French spearmint was imported into Vietnam in 1996 and cultivated in Ha Noi. In the first year, it was cultivated by seeds and since the second year it has been planted by stolons. Every year, planting is done in February – March and the crop reaches full blooming in June. The Russian cultivar is also cultivated in Sa Pa (Lao Cai province). Both samples of Mentha spicata essential oil were analyzed by GC/RI, GC/MS and 13C-NMR. In total, 39 compounds have been identified, 28 in the first sample, 31 in the second.
