Abstract
Dry raw material of both peppermint and sweet basil grown with the application of different hydroponic methods (cylindrical, gully, continuous, classical) exceeds soil culture 1.2-2.7 and 1.8-2.7 times. At the same time a high output (1.6-3.1 times) of secondary origin bioactive substances was observed in cylindrical and classical hydroponics systems due to the high productivity of peppermint and in the case of basil in cylindrical hydroponics system (1.2-2.9 times). For determining antioxidant activity from different quantity of alcoholic extracts obtained from the mentioned plants the more effective is chosen in peppermint 5.0 mg/ml in which case free radical oxidation process of lipids is repressed from 68% to 84%, and in case of basil 1.0 mg/ml from 23% to 31%.
