EVALUATION OF TOTAL POLYPHENOL CONTENT OF THE EXTRACTS OBTAINED FROM SELECTED ROMANIAN PLANT SPECIES

This study focused on the use of native plants as a source of raw materials to obtain hydroalcoholic extracts by two extraction methods, percolation and respectively Soxhlet. The plants used in the study were: ivy (Hedera helix), cocklebur (Xanthium strumarium), wormwood (Artemisia spp), sage (Salvia officinalis) and rosemary (Rosmarinus officinalis).The extracts were chemically characterized to identify bioactive compounds. It was determined their polyphenol acid content (expressed as gallic acid) and flavonoid compounds content expressed in rutin. These are compounds with proven antifungal activity. Observing these values can be seen that both the content in flavonoids and polyphenol acids is higher in species of rosemary, wormwood and cocklebur, which explains their ruse in the Romanian traditional medicine. This indicates that these extracts have major antifungal properties.
