Fenolne kiseline i ukupni fenoli nekih vodenih biljaka
Content of phenolic acids and total phenolics in several aquatic plant species
Abstract:
According to the content of free phenolic compounds, the five stagnant water plant species examined in the present work can be arranged in the following order: Nymphea alba>Lemna minor>Salvinia natans>Trapa natans>Ceratophyllum demersum. These plants contained more of free p-coumaric, ferulic, vanillic and syringic acid comparing to bound forms (ester linked) of these compounds. In addition to these phenolic acids, in the bog sediment p-hydroxyenzoic acid was detected mainly in its bound form. Dissolved phenolics and vanillic acid were identified in the bog water, as well.
