Chemical composition. Anise hyssop numerous contains biologically active compounds: essential oils (1,84-3,32%), tannins (7.48-8,55%), flavonoids (0,55-0,60%), ascorbic acid (0,09-0,11%), free organic acids (0.80-1.00%), polysaccharides (7,25-8,22%), macro- and microelements K, Ca, P, Mg, Si, Al, Na. The greatest amount of essential oil is accumulated during the flowering stage. In addition to the relatively high content of essential oil, it should be noted a significant amount of tannins (tannins). In the grass of Anise hyssop there are two classes of tannins - condensed and hydrolyzable. The last one includes gallic acid which has powerful antioxidant and anti-inflammatory effects.
