    abstract = {The crude extract and 4 fractions of aerial parts of cultivated motherwort (<I>Leonurus cardiaca </I>L.) were investigated for their total phenolic and flavonoid contents and antioxidant activities. The phenolic and flavonoid contents were determined using Folin-Ciocalteu assay and proposed assay of pharmacopeia where as antioxidant activity of samples were measured by 2 tests: DPPH and FRAP assays. Buthanolic fraction showed the highest antioxidant activity with the FRAP value of 1.735&plusmn;0.07 &#956;mol g<SUP>-1</SUP> and DPPH inhibitory percentage of 57.76% &#956;g mL<SUP>-1</SUP> as well as the greatest phenolics content (48.37&plusmn;3.76 mg of gallic acid equivalents g<SUP>-1</SUP>). The highest total flavonoid content was revealed in methanolic-aqueous fraction (50.21&plusmn; 0.65 mg of hyperoside equivalents g<SUP>-1</SUP>). There was a direct correlation between total phenol and antioxidant activities which could introduce phenols as the main antioxidants of <I>L. cardiaca </I>L. extracts.}
