LtEE: L. tomentosa ethanolic extract; LtMF: L. tomentosa methanolic fraction; LtEAF: L. tomentosa ethyl acetate fraction; LtAF: L. tomentosa aqueous fraction; LrEE: L. rigida ethanolic extract; LrMF: L. rigida methanolic fraction; LrEAF: L. rigida ethyl acetate fraction; LrAF: L. rigida aqueous fraction. ND: not determined. -: not detected. Values are means ± SEM of three measurements. Similar superscript letters in the same column do not differ significantly (p > 0.05; ANOVA). * Gallic acid equivalent in mg per g of the sample. ** Quercetin equivalent in mg per g of the sample. *** Tannic acid equivalent in mg per g of the sample.
