•The paper highlighted the compositional similarities and differences between the three extracts of bilberry and cranberry fruit derived from the same Ericaceae family.•A method of antioxidant activity, different cellulose membranes, a Whatman filter and Langmuir – kinetic model were used.•Arbutoside presence in all three extracts of bilberry and cranberry fruit explains their use in urinary infections – cystitis and colibacillosis.•Following these research studies, it was established that the fruits of bilberry and cranberry (fruit and leaves) significantly reduce the risk of urinary infections, and work effectively to protect against free radicals and inflammation. This paper is aimed to select plant materials rich in bioflavonoid compounds, made from herbs known for their application performances in the prevention and therapy of renal diseases, namely kidney stones and urinary infections (renal lithiasis, nephritis, urethritis, cystitis, etc.). This paper presents a comparative study of the medicinal plant extracts composition belonging to Ericaceae-Cranberry (fruit and leaves) – Vaccinium vitis-idaea L. and Bilberry (fruit) – Vaccinium myrtillus L. Concentrated extracts obtained from medicinal plants used in this work were analyzed from structural, morphological and compositional points of view using different techniques: chromatographic methods (HPLC), scanning electronic microscopy, infrared, and UV spectrophotometry, also by using kinetic model. Liquid chromatography was able to identify the specific compounds of the Ericaceae family, present in all three extracts, arbutosid, as well as specific components of each species, mostly from the class of polyphenols. The identification and quantitative determination of the active ingredients from these extracts can give information related to their therapeutic effects.
