Because of the presence of free phenolic acids, especially rosmarinic acid, extracts of Satureja hortensis L.
possess antioxidant and antimicrobial activity. The production of rosmarinic acid by plant cells can be modified
by many factors. In the present study, the changes induced by calcium carbonate and nitrogen application on
rosmarinic acid content, plant growth, and yield of S. hortensis cv. Saturn were investigated. Nitrogen
fertilization significantly increased plant height, fresh and dry weights of herb as well as rosmarinic acid content
and yield. CaCO3 treatments did not affect rosmarinic acid content or yield, while the fresh and dry weights of
herb were increased by applying 5 t ha-1 CaCO3.
