Total phenolic content of Potentilla anserina (L.) Rydb. grown in urban and rural habitats

Abstract

Background. Potentilla anserina (L.) Rydb. is a low-growing herbaceous plant in the Rosaceae family and is prevalent in various types of habitats such as meadows and road-sides throughout Europe, Siberia, the FarEast and Central Asia [1]. Tannins and flavonoids are compounds of interest with notable pharmacological activities [2]. The phytochemical content strongly depends on individual ontogenesis and the environmental growing conditions. Urban ecosystems differ from natural biocenoses and their peculiarities can significantly impact the profiles of bioactive compounds. Aim. To evaluate the amounts of phenolic compounds of P. anserina both in urban and rural areas during different vegetation periods. Methods. Aerial parts of P. anserina every two weeks in the months of June, July and August were collected from the Northern part of Lithuania in urban and rural areas. The total phenolic content was determined according to Folin–Ciocalteu method [3]. Results. The total phenolic content was in a range of 82.11±2.21 GAE mg/g – 112.51±4.72 GAE mg/g and 83.57±0.70 GAE mg/g – 108.74±0.53 GAE mg/g in urban and rural areas, respectively. The results have shown that the greatest amount of phenolic content was determined in during the massive flowering period in the samples collected from both habitat types. At the end of the vegetation period, in August, the total amounts of phenolics significantly decreased to 82.11±2.21 GAE mg/g. Conclusion. P. anserina from urban habitats contained higher amounts of phenolic compounds. The species due to extensive distribution and adaptation could be a sustainable source of phenolic compounds for industrial applications Background. Potentilla anserina (L.)
