Anti-inflammatory activity of four gentian teas and individual compounds on carrageenan-induced paw edema in rats after 1 and 4 h after injection. Bars show the values of edema volume (mL). Values of edema shown are mean ± SD (n = 12). Asterisks indicate statistically significant values from the control (*—p < 0.05; **—p < 0.01; ***—p < 0.001). On cuts—percentage of edema inhibition (A—aspirin, G.a.—G. algida, G.d—G. decumbens, G.m.—G. macrophylla, G.t.—G. triflora, G—gentiopicroside, LG—loganic acid-6′-O-β-d-glucoside, iO—isoorientin, iOG—isoorientin-4′-O-β-d-glucoside, WSPF—water-soluble polysaccharide fractions).
