EXTRACTION OF FLAVONOIDS FROM THE LEAVES OF THE LITTLEWALE LITHOSPERMUM OFFICINALE L. (BORAGINACEAE) USING MICROWAVE ENERGY

One of the possible ways to intensify and increase efficiency extraction biologically active substances from plant materials is use microwave radiation. This article presents results a study influence parameters process on output flavonoids leaves littlewale (Lithospermum officinale L.), belonging Boraginaceae family. contains isoquercitrin, which one key with property tissue regeneration. It was shown that maximum yield target components achieved generator power 100 W exposure duration 2.5 min at field frequency 2450 MHz (specific energy consumption 8.4 kWh/kg). comparable when using conventional convection heating. Microwave radiation provides 16-fold reduction in sum an degree isoquercitrin by 23%. The action leads destruction tissue, contributes more efficient raw materials.
