The essential oils were obtained from Myosotis arvensis L. and M. palustris L. by hydrodistillation and subsequently analyzed by GC–MS. Fifteen components in M. arvensis and twenty-one in M. palustris representing, respectively, 89.63 and 93.19 % of the total oils were identified on the basis of their retention time, mass spectra characteristics and semi-quantitative data were obtained from relative peak area percentages. The 3-methyl-benzaldehyde was found to be the major constituent of both tested oils (42.76 % in M. arvensis and 45.80 % in M. palustris). Additionally, methyl salicylate was a characteristic compound for M. arvensis and α-bisabolol oxide B for M. palustris.
