Nine major phenolic acids (protocatechuic, gentisic, p-hydroxybenzoic, vanillic, caffeic, syringic, p-coumaric, ferulic, synapic) were investigated in 9 species of the genus <em>Polygonum</em> L. The total amount of these compounds equated 65.8 µg/g of dry herb in <em>Polygonum persicaria</em> L., 61.2 µg in <em>P. convolvulus</em> L., 59.1 µg in <em>P. lapathifolium</em> ssp. <em>nodosum</em> (Pers.) Dans, 53.3 µg in <em>P. bistorta</em> L., 42.1 µg in <em>P. mite</em> Schrank, 38.2 µg in <em>P. lapathifolium</em> ssp. <em>tomentosum</em> (Schrank) Dans, 37 µg in <em>P. anrphibium</em> L., 33.2 µg in <em>P. hydropiper</em> L., 31.1 µg in <em>P. aviculare</em> L., and 14,1 µg in rhizome <em>P. bistorta</em> L. Among the analysed phenolic acids, synapic acid (28.6 µg/g) in <em>P. persicaria</em> L., protocatechuic acid (34 µg/g) in <em>P. lapathifolium</em> ssp. <em>nodosum</em> (Pers) Dans, and ferulic acid (21 µg/g) in <em>P. bistorta</em> L., were dominating.
