Description
Summary:Abstract Rhodiola rosea L. is an important medicinal plant, grown in the Arctic regions. Recently, many investigations are devoted to the development of new methods of extraction bioactive components from R.rosea. One of the valuable and common methods of extraction is maceration in the water-ethanol mixture to obtain tincture. At the same time, a certain drawback of systematic studies of the dependence of such extraction efficiency on the concentration of ethanol is noticeable in the literature. In this work data of systematical study of maceration efficiency of water-ethanol mixtures with ethanol content 0 – 97 vol.% at 25°C. Salidroside content and total antioxidant activity were estimated. It was obtained that the most useful for salidroside as well as other antioxidants extraction is maceration with 50 % water-ethanol mixture rot 3 days. These data can be used to organize the extraction process and for further studies in the field of optimization of the processes of extraction of bioactive compounds from R.rosea.
