In this paper we aim at valorising natural bioactive principles from the spontaneous flora belonging to the geographical areas in Western România (Timiş and Caraş-Severin Counties) by isolating and characterising 3 – ramno – glycoside quercitine (rutin) from dog rose (Rosa canina). We accessed different solvent systems for the solid/liquid extraction (alcohols, acetone, benzene, etc.) and then we replicated re-crystallisations. We obtained yellow needle-like crystals that we characterised chemically and physically and chemically. Confirmed extraction yields and purit
