We observed the content of essential oil in the drug of sweet flag coming from 13 localities in the Czech Republic. The amount of essential oil in the drug was higher in the spring crop (0.8-2.6 %), than in the autumn crop (1.0-1.8 %). It was found out that the localities had a statistically significant effect on the amount of essential oils in the drug. The amount of beta asaron in the drug was 0.07-0.41 % depending on the locality. As a result of the correlation analysis a close negative relationship between the amount of essential oils and Ca in water and pH of substrate in the localities of crop was discovered.
