Abstract

The aerial parts of selected Potentilla species (P. anserina, P. argentea, P. erecta, P. fruticosa, P. grandiflora, P. nepalensis, P. norvegica, P. pensylvanica, P. crantzii and P. thuringiaca) were investigated in order to determine their contents of polyphenolic compounds. The results showed that P. fruticosa has relatively high concentrations of tannins (167.3 +/- 2.0 mg/g dw), proanthocyanidins (4.6 +/- 0.2 mg/g dw) and phenolic acids (16.4 +/- 0.8 mg/g dw), as well as flavonoids (7.0 +/- 1.1 mg/g dw), calculated as quercetin. Furthermore, we investigated the in vitro inhibitory effects of aqueous extracts from these species against cariogenic Streptococcus spp. strains. It was found that the tested samples moderately inhibit the growth of oral streptococci. However, all the preparations exhibited inhibitory effects on water-insoluble alpha-(1-->3)-, alpha-(1-->6)-linked glucan (mutan) and artificial dental plaque formation. The extract from P. fruticosa showed the highest anti-biofilm activities, with minimum mutan and biofilm inhibition concentrations of 6.25-25 and 50-100 microg/mL, respectively. The results indicate that the studied Potentilla species could be a potential plant material for extracting biologically activ...Continue Reading
