Abstract

The aim of this thesis was to find the content of rosmarinic acid (RA) in the selected varieties of sage (Salvia officinalis L.): Krajová, Purpurascens, Berggarten, Tricolor, Icterina and Alba. In the monitoring years 2013-2015 and two collection dates was found that the highest RA content was in Tricolor in 2013 (30,084.65 mg*kg-1) collected in the first term. The lowest value was recorded for the Berggarten (9,000.5 mg*kg-1) in 2015 in the second collection date. The highest average RA content was found in Tricolor (19,605.82 mg*kg-1), while the lowest RA content was in Berggarten (14,610.71 mg*kg-1). When the terms of collection were compared, there were confirmed statistically significant difference in RA content in the monitored varieties of sage (P˂0.001) between 1st time of harvesting (22,516.08 mg*kg-1) and 2nd time of harvesting (11,155.83 mg*kg-1). Within years was the lowest content of the RA (13,562.74 mg*kg-1) found in 2015 and the difference in the RA content this year compared to 2013 and 2014 was statistically significant (P˂0.001). Average RA values in the monitored varieties of sage in 2013 (17,624.12 mg*kg-1) and in 2014 (17,522.69 mg*kg-1) were not statistically significant. These results follow, that the content of RA in sage (Salvia officinalis L.) statistically significantly affected the variety, time of harvesting and growing year.
